Got a bit of a problem with my MSN Messenger. It worked up until my format/reinstall, and now, it refuses to believe my username/password are correct. When I try to sign into a passport enabled site on the web, it tells me my email address isn't registered as a passport. When I try to register it as a passport, it says it already is registered...It's working fine on my laptop with that email/password. I've tried to reinstall, no luck. Any ideas?
