I have the same problem, with a couple of my purchased songs and a movie, all of which I recently downloaded. My songs have the artwork but don't play and the movie doesn't play at all (no video or sound). I recently changed my itunes account because the old one suddenly stopped working and all the things I have purchased through the new account won't play. I was wondering if anyone knew if the new account is reason why, and if so how can I fix it?
