xbox 360 vista extender s

I have the public beta 2 of vista and a Xbox 360. When I try to connect..I get the launch screen and it briefly goes to the main menu, then shuts and says "closing desktop".... then the 360 leaves this error:
"The Xbox has disconnected because an application has launched UI unexpectedly. Would you like to reconnect?"
It then continues to do this over and over.......
Any suggestions???

Are there any open applications when you try to connect the XBOX to Vista such as Media Player or Media Center for example? Try closing out all applications and connect again. If the problem persist, I suggest reporting the issue. For Feedback: http://go.microsoft.com/fwlink/?linkid=55160

You might also want to post this in the Media Center newsgroup where others might be experiencing the same and be able to give you better answer or possible work around: http://windowshelp.microsoft.com/communities/newsgroups/en-us/default.mspx?dg=microsoft.public.windows.mediacenter&lang=en&cr=US&r=569f5f5e-087a-4748-bf27-c6829af79b0d -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
