All of a sudden, I cannot access my Yahoo Messenger. It pops up the sign on screen, then I sign in but it immediately flashes from "Welcome ScrappyKi" to grey sleeping smilie with my contact list greyed out.

I have tried to reboot. Remove and reinstall. Changed the firewall/proxy choices (i.e. no proxies, use proxies, firewall no proxies, firewall use proxies) with no luck.

I'm at a loss!!!
