I've had MSNM running for a while as of late, and I don't want it running. I believe I made a fix, but I don't quite know...

See, the next problem is that it's taken over. And I don't want it running anymore. Whenever I right click on the icon in the taskbar which isn't there at all, but when I "call it out" I can't exit it. It just says "There are other applications currently using features provided by Windows Messenger. You must close these other applications before you can exit Windows Messenger. These applications may include Outlook, Outlook Express, MSN Explorer, and Internet Explorer."

HELP!!!
