Well i installed Vista this morning, all running fine except i can't seem to add an extender to Windows Media Center. It says i have to enter the setup key which is located on the xbox 360, which i have done. Then when it configures it stops at Seaching for extender then i get this. I know my setup key is correct and i've set the firewall to allow UPnP Discovery. But i'm not sure if the extender is connected tyo my computer or not, how do i find out?
