Uninstall it, reboot then reinstall it.

If that fails try live messenger 8.0.

sounds like you need to remove the old msn and go to www.msn.com and install from fresh
it could be that you are using a cracked version of windows xp or your computer has a virus like trojan horse, if thats not the virus you have something much worser. The name of that cracked version of windows xp is called "Window Xp Sp3 Special Edition 2006". Its a cracked version of the operating system and you can do all of microsoft's usual updates. You don't have to use a activation code. All you have to know is the CD key.
