E-8306 on XDJ-RX2

Hoping Pioneer can work with me to resolve this issue.

With two of my playlists specifically, none of the songs work. When I load them on the deck, I get a message containing "E-8306 No File". The tracks aren't new, I've been playing them for months and never had a problem.

They are all MP3, 48000Hz, 320.00 kbit/s.

I have updated the firmware to the most recent version (1.38), and the software on both my Macbook and Rekordbox are up to date.

Thanks.
