Hey guys, video chat in iChat suddenly no longer works. Everyone I try to video chat with gives me a "user not respond error". I've tried rebooting, power cycling the router, plugging it in directly to the ethernet connection, etc. and nothing works. My roommate who has a blackbook isn't having any issues and we use the same router. I did upgrade to iTunes 8.0 and Quicktime 7.5.5 but neither should be interfering since he did as well and isn't seeing any issues. Can anyone help me get this working again//offer up any tips on if and how i should un-install-re-install ichat?
