When i try to transfer cue and grid info from usb back to rekordbox it get stuck at 1%. If i try to close it i get spinning wheel and rkdb freezes. History was updated succesfully even tho the date was set with current date (so 3.3.) not 27.2. when history was created. Syncing from rkdb to usb works flawless, but when i try to update it back it gets stuck. It worked both ways for 2 months now and also nothing is wrong with usb key. Rekordbox is version 4.0.8 and i'm on latest version of el capitan on 2012 macbook pro 13".
Can anyone suggest what else to try?
