Help!! 
Haven’t used my Traktor pro for a few months but recently got back on to find most of my playlists gone, random artwork missing,  bpms at 0 & tracks unable to play with error message. 
Have deleted my collection & have reimported & am in the process of analysing my track collection. 
I have all my music on Apple Music ( which I suspect is the culprit) 
i am not particularly techy so please be kind & keep it simple. 
many thanks 
Issy
