Why I cant login NOT USING Windows LIVE ID if I have ONE?

Wht I cant GOTO TO OROFILE PAGE, Bacuse of error: Server error ./ is not a valid path name?

Why it is so stupid that 12-yrs experienced .NET can do NOTHING about it?

Why I'm stuck with this LOGIN problems?

Why I CANT CHANGE MY LOGIN, if it is errornnous, AT LEAST?

P.S.

If you think i have not tried, Saferi, WinXPSP2, coffehouse, Even IPhone, you are wrong, I TRIED ALL THE STUFF....

Why channel9 sucks? I do not want it to be so user UNFRIENDLY!!!!
