New update PMP seems to have issues...

Since I updated my PMP on my Mac Mini (Late 2012, El Capitan), music doesn't seem to play continuously anymore i.e. it will play one song then stop...
Thats the same if it plays in the app, cast from my laptop or phone, normal play or shuffle... )':
Also, the icon for the app doesn't seem to work any more, its just the pencil/brush/ruler/paper symbol from Apple..
Anyone else had this...??? It was flawless before the update...
