Vista - Messanger Error code :80048820 + Microsoft website problem

hello everyone ,
recently i have strange problem , my messanger suddenly show me that error without any reason.i searched the web and saw all the solutions that may fix this problem but none really helped.

now the second problem i think may be connected somehow to the first one. when i click on MSN.com page on "messanger" option or the web messanger it shows 404 error that of course cannot be real only can be problem in my computer or the windows itself.

i have router DIR DLINK-300 , everything working ok on the second computer so it cannot be router problem.

ty for your answers.
