URGENT! E-8305: Unsupported File Format when playing on CDJ2000NXS

I got this error for the first time in a club the last week and after some research I realized it was because of the bit depth of the tracks I have since they were all 32, 48000Hz and 3072kbps. I have a huge library with set cue points and everything that I've been playing for long time so I don't have the chance to delete the songs and download them again in the correct bit depth.

I have a gig in 2 days and I am desperate to find a solution to this. Is there a way that I can fix it in the Rekordbox software or is there any softwares out there that I can just change the bit depth??

Thanks in advance
