E-8305 Error CDJ 2000 Nexus

Hi there.

So I m geting this error on random songs which I played for a lot years and always working, but in last 2 gigs while I read the track, they freeze my player and quickly show this error and dissapear. I can still search tracks on that player which is frozen but can't read it beacuse everything blinking, also hot cue button is blinking. Was work with CDJ NXS2 for a year in other club and never happened to me. USB is Kingston datatraveler 100 3.0 32gb, works perfectly for 2-3 years and there is a 50 playlists, and 2000 songs, most of them have 2-3 hot cues each. Players have newest update 1.41, and I was rekordboxed it on newest rekordbox if I remember 4.3.1. Pissed me off cuz I need turn of and turn on player for continue work.

Thanks
