A simple one I hope!

I ran into the External Cam Gone Wild thing (where it just kept spinning and wouldn't stop) and when I mentioned it in a post someone said they'd "reset" the cam on their PC by alt-tabbing out of the game (or hitting the key that brings up the Start menu, which essentially does the same thing) and dropping it to the task bar. When they brought the game back up, the cam was back to normal. Worth a try anyway.
