Hi, I just updated Rekordbox to 5.3.0 and have now lost ALL my data from my USB's - I have my files on USB (with 1 USB and 1 SD card as backup) - my main files on the laptop are used in Serato - So, after the upgrade I put my Primary USB in and opened up Rekordbox and had the message that the Configuration database was corrupt and did I want to delete - I clicked NO and Rekordbox would not recognise my USB, I tried the secondary and the SD card and all the same. So, on the Secondary USB when connected I clicked yes to remove the config database - this opened up the USB and my files weren't visable, no playlists, no folders, no history - yet I could plug my Primary USb or SD card into my CDJ2000 and everything was there. Long story short but after inserting the Primary and SD cards Rekordbox has managed to work but I have lost ALL my cues, loops, history and playlists! Any ideas where the hell these reside so I can get them back??? I have now started to re-analyse all my tracks in preparation for a gig on Thursday where I need my USBs - any help would be much appreciated. Cheers
