- You get an error message during installation "(com.apple.installer.pagecontroller error -1)" (Mac only)
Try downloading using another browser or unzipping using a different utility. This is typically a corrupt or incomplete download causing this issue.
- You get an error message "MFReadWrite.dll not found" (Windows only)
You are missing a service pack update; click one of the following links depending on your operating system:
Windows 7 / Windows 8 / Windows 8.1 / Windows 10
- rekordbox installer won't run (Windows XP and Vista only)
Sorry to say, you're going to need to upgrade your operating system as XP and Vista are no longer supported as of rekordbox 3. See the system requirements here.
- rekordbox won't start
Are you overclocking? Does your computer have performance management software such as MSI Afterburner or RivaTuner running? Be sure to disable it before launching rekordbox.
- rekordbox crashes on startup
Try disconnecting USB devices (especially audio interfaces, hard drives, flash drives, SD cards and/or card-readers) and try again.
- rekordbox has troubles starting / loading tracks / it crashes...
It could be that your database is corrupted or damaged and you need to try loading the backup database. Ensure rekordbox is closed and find your database in the following location:
Win 7/8/10: C:\Users\yourusername\AppData\Roaming\Pioneer\rekordbox
Rename datafile.edb to datafile.edb.old
Rename datafile.backup.edb to datafile.edb (removing .backup)
Restart rekordbox and see if it opens. If it does, the main database was corrupted and the backup was working okay.
If it does not open, go back and rename ALL of the datafile files in that folder to .old and restart rekordbox once more. If it does load, both the original and backup database were corrupted and you will have to re-import your songs once more.
- rekordbox rejects your serial number
Effective version 3.0, a serial number is no longer required to use the basic (export mode) operation of rekordbox. You do, however, require a KUVO account, which can be done as part of the registration process at rekordbox.com
If you are trying to enter a rekordbox serial number you obtained with the purchase of a CDJ, that number was valid for rekordbox 2.x and is not eligible to unlock rekordbox DJ (performance mode). You can download rekordbox DJ and use it in a trial mode for 30 days for free, after which you can subscribe to a monthly payment or purchase a license.
Be sure you enter the correct license key and include the dashes between the character sets as emailed / written on the info card. Beware a copy-and-paste from your email not working properly; try manually typing it in.
- You get an error message "Check Internet Connection" and can't log-in to authorize rekordbox
Go to kuvo.com, and once you are logged-in, click Connect, then Edit Profile (or try clicking this link to get there directly) and scroll down. You'll see this:
Click DOWNLOAD ACCOUNT KEY and it will prompt you to download the djprofile.nxs file. Save it. When you open rekordbox you can select that file to open the software when prompted.
If you have a problem with the downloaded file, please try using another browser - sometimes Safari corrupts the download.
- rekordbox doesn't show the waveform properly or crashes after a few minutes
Try toggling the “Use high functional waveform drawing” setting from the Preferences, under the View tab.
You may also need to update the drivers for your graphics card / chipset. Please use the following manufacturer websites to check for the latest drivers rather than simply using the Windows Update utility, as it may not have the latest version available for your computer:
- The fonts all look weird within rekordbox (OS X)
If you are using FontExplorer or another font manager, it may have messed around with the default system fonts. Please uninstall that application, and then from the system Font Book application, select 'Restore Standard Fonts' from the File menu. Please note that this will disable non-standard fonts in your system (they are put aside in the Fonts(removed) folder).
- The fonts all look weird within rekordbox (Windows 10)
Some of the fonts used by rekordbox that were available in previous versions of Windows as default fonts were removed by Microsoft, but can be re-added for free. Follow the instructions in this article for more information.
- You can't get your players to link
First and foremost, you need to connect the players with the LAN connection, not the USB. That's only for use as a soundcard and/or MIDI/HID control for software. The main problem with not being able to load tracks to your players via the LINK function is typically a firewall. This thread has walk-through videos for Windows and OSX on configuring the firewalls. Note: the windows videos are missing, but follow this info:
Here's what you need to allow through the firewall (Windows or otherwise):
C:\program files\yourusername\rekordbox version-number\edb_streamd.exe - TCP
C:\program files\yourusername\rekordbox version-number\psvnfsd.exe - UDP
C:\program files\yourusername\rekordbox version-number\psvlinksysmgr.exe - TCP
C:\program files\yourusername\rekordbox version-number\rekordbox.exe - TCP
You need to configure this each and every time you install a new version of rekordbox if your firewall is not set to alert you to new connections, otherwise you'll see a pop-up alerting you to the connection and you simply allow it through (and set it to remember / always allow it).
- Try disabling your firewall
If you still have problems trying to configure the firewall, try disabling it to see if perhaps it's a setting or permission within that's blocking it. An important note If you are running Windows 7, 8, 8.1, 10, you may need to change your network type, see instructions here on how to do that (this link shows how to go Private > Public; you need to do the reverse, changing a possible Public network to a Private one, either Work or Home.) There separate configurations for each of the Private / Home networks and the Public networks.
If you are using the CDJs / DJM connected without a router, you will likely find the IP addresses are self-assigned in the 169.254.x.x range and the network type will default to Public - Unidentified. Because public networks are more likely to have outside problems, they are subject to more stringent security and limited connections. Be sure to test by disabling the Public firewall as well, or follow the instructions linked above to convert the network type.
- The firewall isn't the problem but it still won't link properly
You may have a network configured for sharing. Check this page for Mac or this page for PC for instructions on how to disable the network sharing. You may also try disabling any additional connections your computer has. For example, if you have a wired and wireless connection, try disabling the wireless during the testing of the Pro DJ Link to see if it helps.
Alternatively, you may be running security software which may also act as a firewall; be sure to check any 3rd party security software and configure or disable it.
- You did that and still have problems with the link
It could be the network hardware (usually a router) you're using is filtering the packets; first try connecting a player DIRECTLY to your computer with the network cable.
- I did all that but it STILL won't link
Have you scanned your computer for malware and/or viruses? I recommend maintaining your computer's security with Malwarebytes Anti-Malware, ADWCleaner, HitMan Pro and CCleaner. I am not providing links to these applications as they may change over time - just Google the name and you'll find them. They're all have a free version but some also offer a paid premium version - the free version will work just fine. Be sure your system is not infected.
- You can see the players in the link section, but dragging and dropping tracks there doesn't load them to the players
If you've followed the instructions above re: the firewall, try power-cycling your players and press the blue LINK button to see if rekordbox shows in the list of link items, or on a CDJ-2000nexus or CDJ-900nexus model, press the rekordbox button on the player, then rotate the selector knob and accept the connection onscreen.
- Your wireless internet doesn't work while linked to the players / mixer
This is predominantly a Mac issue, so this is a Mac fix -- open System Preference, open Network, at the bottom of the connection list there is a settings drop down, select 'Set Service Order', then drag Ethernet to the top. Click OK, then Apply and now you should be able to use rekordbox Link, even with Airport on and connected to the internet. Depending on your router / network configuration, you MAY NOT be able to use your computer wirelessly with players/mixer that are hard-wired to your wireless router / access point as some of these devices do not permit proper network communication between wired and wireless networks.
- Your music isn't importing properly
Chances are good your MP3s have errors in them. It's more common than you think. Go and grab one of theerror checking utilities in this thread, run it to check your files, and try importing again. If it's not MP3s you're having problems with, are you sure the filetype is supported? Older songs purchased from iTunes which contain DRM will not be imported.
- Your M4A file won't import/play
M4A is a wrapper for various encoding-types. Only AAC encoded M4A files are supported. Check that your files are AAC, or convert them using iTunes or another utility to a filetype which is supported.
- Your playlists (M3U, PLS) aren't importing properly
Not all playlists are created equal; some are local reference and some are absolute reference. If it's problematic, import tracks directly instead or re-build your playlist files.
- Importing and analyzing is slow, is it multi-core optimized?
As of rekordbox 3, there is multi-core optimized analysis! If you find that it's only doing one track at a time, go into Preferences > Analysis and change the Concurrent Process Mode to Performance.
- Your album artwork is missing
If your album art shows in other programs but not rekordbox, it's likely just a problem with the way it was embedded to the file. Read this post for some help there. Album art is notorious for being problematic, especially from Beatport (love the music, hate the artwork issues). Always scan your files for errors before importing them.
- Your music is missing
If you see a little yellow exclamation mark, you've either moved or deleted that song, the source drive it's on is not connected or it has been damaged and can't be loaded. It may also be that the music you tried to import is in an unsupported format. First try relocating it by right-clicking and select Relocate. You can batch-relocate by selecting ALL your music and then attempting the relocation process.
- You made changes to the song's tags in some other software but rekordbox isn't reflecting those changes
Like most programs, the database doesn't re-crawl your files to automatically refresh the information. You need to right-click on the file to have it Re-scan Tags, which will update the info.
- You set a cue point for a song, but the next time you load the song, the cue point you had set is missing
When you use the rekordbox player to set a cue point, all you're doing is setting the cue for playback in theplayer, not storing an initial cue for that song in the database. Try setting the a memory point or hot cue instead.
- You imported your music but nothing is showing up when you connect your hard drive to the CDJ
Did you also export your music? rekordbox operates similar to iTunes where you add your music collection to the software and then export it to a device (in the case of iTunes, you export to an iPod, for rekordbox, that device is a hard drive, flash drive or SD card). Once you export your music to that device (I suggest you use a SECONDARY device, not the same drive you imported your music collection from; if you were to export your entire collection to that same device you'd effectively double the space used on that device), you can then take it to a CDJ and your rekordbox database will be read.
- You can't export your music
Do you have a FAT, FAT32 or HFS+ drive connected to your computer via USB? If so, it will appear under the Devices tab. Drag and drop your files from your collection to the device there. Devices connect by FireWire or Thunderbolt will not appear as export devices.
- You've exported files to your device but the CDJ won't recognize it
If you're on OSX, the problem might be that you've got it set to GUID instead of Master Boot Record. See this video for instructions on how to properly format the device.
- You've exported files to your device but the XRJ-R1 won't recognize it
Did you choose the R1 database type prior to exporting? You need to be sure you're telling rekordbox the device you're using is an R1 and not a CDJ. Go to Preferences > Device and change the drop-down "Create library exclusively for:" to show XDJ-R1. If you have previously used the export device for a different database type (eg. CDJ), you will need to re-export or use a secondary export device (which is my recommendation).
- Your rekordbox exported library isn't working with your player
That's possibly because your player is not supported. Only the CDJ-2000nexus, CDJ-2000, CDJ-900nexus, CDJ-900, CDJ-850, CDJ-350, XDJ-AERO, XDJ-R1 and XDJ-RX currently support rekordbox libraries. It will NEVER work with a CDJ-1000 or other older generation player, not even to call up hot cue points from the SD card, sorry. That said, a CDJ-2000 can can call up waveforms and memory points for audio CDs from SD cards from a CDJ-1000.
- What about my MEP-7000 library?
The beauty is that the newer CDJs will support the library of the MEP however the MEP can not read rekordbox exports, sorry.
- You want to export to a CD/DVD instead of a USB device
Sorry, it doesn't work that way. The CDJs can't read the rekordbox database from optical media. You can still use a media device to store waveforms, memory points or hot cues from a CD, the way you could with a CDJ-1000, although these will not be available over the player link.
- You can't find the BPM or KEY or ... field
If you're looking for it in rekordbox, right-click on the column headers you can pick from the list.
If you're looking for them on the CDJ, chances are you simply didn't tell rekordbox that you wanted to enable those fields. This video shows you what to change.
- You got an 830x error message
Are you using the latest software and firmware? Were you linked at the time? Have you checked your drive AND the files therein for errors? Can you reproduce the error? If you are a PC user, when you formatted the drive, did you format it TWICE with a non-Microsoft utility? Did you read everything above first? Still having problems? Go to the bottom, copy and paste to a new thread, fill in the answers.
- You click the play button but no audio is heard, the audio doesn't play back
It could be that your audio device settings are outside the supported range. Within rekordbox, go to Preferences > Audio and change your sample rate down to 44100 Hz.
