Hey a few months ago, Windows Live Messenger was update by Microsoft.
Afterwards, it would not let me log in. It gave me this error and took me to this page:
Error 8100030d: Cannot Sign-in to Windows Live Messenger
That page did not help at all.
This page worked the first time:
How to perform Clean Installation of Windows Live Messenger
However, it was still very annoying. And I complained the first time it happened.
Well, Windows Live was updated by Windows Update again, and yes, you guessed it, this same issue happened again.
A second time is just unacceptable.
Especially since neither of the websites above fix this. I expected the second one to fix this again, but alas, it does not!
