Errorcode: 0x800B0004 or 800b001 (with MSN Messenger 7)
"Signing in to .NET Messenger Service failed because the service is temporarily unavailable. Please try again later."
This error is usually caused by Windows being unable to find a .dll file that is needed by MSN Messenger for security.
To resolve it, you can download this file and run it. It will register all the required .dll files which means Windows can find them.

thanks to Bigball forums for this

[FONT="Franklin Gothic Medium"]Just in case anyone wonders, there isn't a key called 'the any key'. Also the latest version of msn messenger for windows is 8.1[/FONT]
