XDJ-AERO RECORDING PROBLEM.

Hello everyone! I'm having an issue with the recording option of my xdj-aero. I'm using a kingston 32 gb pendrive (that has more than 20 gb of free space) and all of my tracks have been analyzed with rekordbox.

While I'm mixing, the yellow light of the USB starts flashing and a bit later the red light of REC starts flashing too and I see the words "rec error" on my display.

Note: I have already used this same pendrive for recording before and I didn't have a problem.
