E-8302 cannot play track (c2df)

Hi, today i'm updated rekordbox from 4.1 to 4.2 and got some problems with loading tracks. 1. tracks cannot be loaded directly from rekordbox to my cdj's (2000nxs), but it can be loaded if i load them directly from cdj, using prepared playlists in software. 2. all hot cues became LOOPS, but in rekordbox they are normal HOT CUES. I tried on booth systems OSX and WIN, problem still exist. When i'm installed old version of rekordbox (4.1.1) problem was solved.

P.S. I'm using my rekordbox with LAN connection in EXPORT mode only.

Sorry for my english)  Thank you!
