hi, i have a macbook coreduo, 1gb of ram, all that good stuff. now, since i have gotten my mac, over 9 months ago, my ichat has never worked, and it always says, Error connecting. now i tried to hook up a xbox live vison cam, which i can only get to work with a shareware app. So i guess i have two questions, how do i get my ichat video chat to work and how do i get ichat to recognize the vision cam. any insight will help, thanks!
