Rekordbox 4.1 Update Wireless Device Issues Playlists Deleted

 I stupidly updated to 4.1 without checking what everyone else thought first!

All seemed OK until I connected my iPad (backup for when things go wrong) I updated my playlists but when I went back onto the app all my playlists have gone!

 I have tried to import them again but I just get an error message. I'm now worried tonight's gig could go horribly wrong!

 Anyone else in the same position?
