It's happening to most everyone. Googleing hasn't been much help. They talk about faulty ram and corrupt or over heated hard drives. It's neither. If you only d/l 1 at a time it seems to shut down alot less often. Also when it shuts down, about 1 in 4 times it reinstalls bearshare and changes my settings back to default. I've tried older free versions, older lite versions, and older pro versions. Same problem. Sorry thats all I know for now?? PB
