More of the Same
I have a freshly installed copy of Windows 7 64 bit, and I too am having these issues. It is driving me crazy trying to figure how it works. It shows the stream for a second, goes to an ad, then crashes when its over.
I have noticed that the ad is foreign. I thought it could be a virus or something, but given that this is a clean install and the only sites I've been to is getting Java, Flash, and Firefox.
