Everything was working fine for a long time, but recently it's stopped.  I got a new iPhone 5  and set it up... It "looks" like everything has worked fine, but when I go to play a local file that is on my Mac Desktop on my iPhone 5,   Even though the playlist is setup for offline playing, and there is a green circle with the arrow in it.  Whenever I go to play it on my iPhone I get the error dialog box....

"Track Not Synced"

If you own the track, you can sync it from your computer"

Yes, the synching seems to be working.... If I add a new local file to the desktop... it replicates to my iPhone (with green circle) but still won't play...

Spotify songs work fine offline

Help!!!! Frustrating
