Thanks Mike M and zachd for your replies. The problem has gone away,
apparently related to refreshing my licenses, but I did find it odd that
things would play fine in Media Player but not Media Center when I was
having the problem. I forgot to mention that if I played a specific song
downloaded from Urge in Media Player and watched it retrieve the license
info, I could then play that track in Media Center without issue.

This morning while refreshing/re-reading monitored folders in Media Player I
saw a message saying Media Player needed to refresh my Urge licenses (can't
remember exact wording) and that if I said 'Yes' it could do this in the
background. I did answer in the affirmative but the process didn't seem to
advance and wouldn't allow me to continue doing anything in Media Player so
I cancelled (a little concerned).

Since that happened though, songs I've tried so far now play in Media Center
and I notice that when I play any Urge track Media Player doesn't seem to
need to retrieve any license so evidently at least some part of that process
completed....

All's well that end's well I suppose!
