Retrieve Collection

Hey! I’m hoping someone can help me retrieve my Engine Prime Collection. I was clearing some space on the HD and must’ve deleted Engine database files. I’ve now recovered these (think) but the Collection hasn’t restored.

All my Music is still on the Mac and visible via Engine Prime, it’s just no longer in the Collection.

Any help greatly appreciated. Really don’t want to re-import all the tracks, and then have to rate, loop, cue point, playlist etc.
