Hmm, check the sounds. What is the bit rate? (sorry, it's late and I have an exam in 10.5 hours, and can't be of much use for the next 30 hours or so)
Sometimes if the bit rate is off, it crashes. Others it just doesn't play properly.
If it is set at the "correct" value (I'm not 100% sure about the bit rate, but I think it's 352 kbps or something, but the settings are 22,050 Hz, 16bit Mono, 43 kb/s), it's probably the animations that are messed up, and I'll take a look at it in particular to see if I can replicate the problem on Friday.
