hey guys, i've probably posted this in the wrong area, but what the heck..

erm, my iTunes has been perfectly fine - i.e. yesterday i was on it, although today, when i just wanted to chill and listen to some music, the icon bounced a few times when i clicked it, then it stopped; showing it had opened.. it did not open however, and when i right clicked on the icon it said Application Not Responding.. :/ i'm running Snow Leopard and on an iMac if that helps?

cheers guys
