Synchronize files question

I asked for help with my Media Player loading unwanted picture files in a separate post.  A related problem is that a ripped CD file won’t show up in the files on-screen but is still in the Clip+ and none of the tracks will play.  The tracks are locked in “pause” and will not play.  I have tried deleting them one-by-one in the Clip+ but they don’t go away.
