I have recently upgraded from Vista to Windows 7, I did have problems initially with Windows Media Center, but these have been resolved. My webcam has now stopped working, when I update the drivers it tells me everything is up to date. When I try to set up audio and video in Windows Live Messenger, the speakers work fine but I get the following for the webcam: 1. Default 713 x BDA Analogue Capture - I get a black screen. 2. USB 2.0 Camera - I get "Cannot connect to this webcam. Close any programs that may be using your webcam and chose set up audio and video to try again".
