My Live Messenger is stuck in a constant state of signing in, the green and blue guys keep flashing, but do not sign in. I can't even cancel the signing in. when I close it and re-open it immediately says reconnecting, although I don't have it set to automatically sign in, and when I click cancel, it changes to signing in, and then when i click on cancel it has no effect. My AVG is updated, and it says the computer has no virus. What can I do?

I would suggest to un-install the messenger and download the latest version of live messenger and install it. It should fix the problem.

I'm going to try that, thanks
