hey im having the same problem ever since windows live messenger 9 came out (not beta) i installed it and it was running smoothly but recently i could not sign into it but once it worked and now im back to square 1 again it happened when i installed the new messenger plus which was just released recently but i think it is windows live messenger 9 as the last time it happened was before messenger plus.
can someone help me find a solution please

ps i knw the basics so dont need to ask me to forward it through my router or allow it through my firewall as im well aware of all these factos cheers
