Windows 7 - windows 7 activation error 0x80072+messenger error

hey,i am new here so i may be posting this in a wrong forum...

I am having problems with windows 7 activation and windows live messenger.. i was having problems with windows live messenger but uninstalling and re-installing didn't help so i formatted my pc with windows 7.. now i am having problems with my windows 7 activation ( it gives error code 0x80072EE2) and also i am unable to log into my widows live messenger or facebook... please help me...

NOTE:I HAVE DONE SEVERAL FORMATS DUE TO BOTH ACTIVATION ERROR AND WINDOWS LIVE MESSENGER ERRORS BUT IT DIDN'T HELP AT ALL, I HAVE EVEN DONE SEVERAL SCANS FOR VIRUS BUT THAT DIDN'T HELP EITHER, MY MESSENGER SHOWS THAT I AM NOT CONNECTED TO .NET SERVICE.. AND I AM ABLE TO BROWS THE INTERNET EXCEPT SEVERAL SITES

Do a clean install. Do not install anything extra like Messenger. If everything works, install programs one at a time and make sure that it works, first,before installing the next.

When you install do not give your key number. When everything is installed; programs etc and it works, Give your number then.

well, i have done that several times with clean installation but that didn't help.... and yeah my messenger was working till yesterday but after that it didn't work....

Try this: You may encounter temporary connection-related errors when you use Windows Update or Microsoft Update to install updates

It might help if you try a newer version of the messenger
