Mine too will start to freak out, play distorted and not stop. I have found that if I hit the escape key and wait it out, eventually (most of the time it will stop) I have noticed that when this happens my processor is in major overload. To avoid this sometimes I can turn off McAfee (a major memory user) with the task manager and any other memory suckers that I don't need at the time. This helps but the only way Iv'e found to get those songs/styles to play is to open them up in realband once they are finished and then they don't eat the processor.
