[xdj-rx] Tracks not loading after upgrade v2.21

Hi Guys,

I hope you can help me with the following.

I recently updated my xdj-rx to firmware version 2.21. Then I got some troubles with loading tracks.

 When I start loading my (previous ok) tracks into the deck after a few songs, or right at the first song, a track is unable to load. The display will pop “track now loading”. After this more tracks start to fail up to a point noting works anymore.

 I’ve made a video to show you: https://youtu.be/Fqgxw3fJRfY . Sorry for the 90degree. The problem occurs after about 36 seconds.

 To solve it I tried

• to flash the firmware again. > It wouldn’t let be because it already has the latest version
• to flash the old firmware back > wouldn’t let be because there is a higher version installed
• Use another USB stick (I am using a sandisk cruzer blade 64gb, fat32 formatted) I tried with a sandisk extrebe usb 3.0 32gb, fat32 formatted. > problem still exists
• I analysed my playlist with Rekordbox exported again to both sticks > problem still exists
• I rebuild my entire playlist fresh > still no good

 At this point I don’t know how to fix it anymore. Do you guys have suggestions for me to fix this? I would really like to DJ again.

I’m running Rekordbox v5.3.0 on a windows 10 machine.

Thanks in advance,

 Ruben
