usb 3 DDj RZ and rekordbox

wow, you got yours early, by me they wont be around till late October, so another week or 2.
what error are you getting? What OS are you on?

yea i got it very first, am on OS.10.9.5 the error is am trying to update the version of my ddj.rz firmware to ver.106 but i keep on getting the , An error has occurred, it was not possible to update the program . and am starting to think its a pioneer problem cus its the same error on all my three macs.

Have you tried removing the RZ driver fully, then re-installing it, from the preferences within the Rekordbox software preferences? See, I had a similar issue on PC, and I removed the DDJ-SZ driver, then started RB with the controller not connected, then installed it from the preferences>Audio>then under the "audio" portion of the menu, click driver, and chose in my case SZ, in yours the RZ will be likely. Now, even after I did that, I had to restart for it to detect the SZ connected.
Just anecdotal, but worth giving it a whirl.

yess have tried that to, still cant update the firmware to ver.106

Would you try this and tell me whether it works or not:
