Hi

I'm having the same problem - about half the songs I download into my Library won't play - even though they show in the Library! And I can't delete them without rebooting. Those I can play, play beautifully.

All the songs are MP3s - my anti-virus won't let me play .wma songs.

I've downloaded the VLC player, as per LOTR's suggestion (and link), but it unfortunately doesn't appear to have solved my problem.

I'd appreciate any help anyone can suggest. Thanks.
