It lives! It lives!

The first suggestion (starting with no playlist) solved the problem. I'm a bit puzzled now, though. That question implies that the problem was with the track it was trying to play. However, I hadn't added any new tracks any time recently, and I'd played through every track on the player multiple times. Should I suspect a problem that hadn't managed to crash the player app previously, or that a file has gone bad? How should I go about locating a problematic file without listening through every song on my player? (Not that I have a problem with listening to everything, but it'll take a while )

Thanks again to everyone for all the help!
