USB plugged in in XDJ - Cannot find master file DDJ-RB

Hi all,

I had a party few weeks ago where I plugged in my usb in a XDJ.

First of all it was not recognizing my music and playlists at all.

Second of all, after that, Rekordbox is not finding the master file anymore when I plug in the usb on my macbook to connect with my DDJ-RB.

I don't see any playlists or music in Rekordbox anymore, but it is luckily still in my usb folders.

Could you please help me to retrieve the master file?

Kind regards,

Stephen
