so this was real fun tonight
out of no where i all of a sudden had a few tracks greyed out on the CDJ that i couldn't click on to load and if i tried to load it via Rekordbox through link I got:

these are tracks i play all the time for years, including this afternoon but then at the night job, I get this. Nothing has changed anywhere, same system. laptop, FW, songs, software versions, etc.... I'm on the latest of all
at first i saw this, you can see VIVIR MI VIDA is greyed out,

so during dinner i threw on background through iTunes and rebooted the deck and then it was playable BUT now a few other tracks that were fine before the reboot could not be be played. you can see now the track is not greyed out after a reboot 
but now "LIKE A DRUM" cannot be played which WAS playable before the reboot

here are some pics of the "info" from the tracks i was not able to play that i saw, I'm sure there were more but these were the few i saw and then panic set in, thank god i was able to quickly convert them to MP3 and play without my sets being messed up. All tracks are MPEG4 AAC 320K 44.1KHz



Heres it all caught on video happening again, this is so aggravating never knowing all of a sudden if a track will load or not
