Hi

I plugged the USB into my PC and pressed something. Which caused the playlist on the USB to disappear. This causes the music list on the USB to disappear.

But my USB memory is still full.

What can I do to get my playlists back to normal on my USB?
Now I'm very stressed and don't know what to do.


Thank you very much in advance! T-T
