Please HELP!! I can't uninstall msn through the control panel!!

I'm new here and this is my first post..

The problem is that I accidentally deleted all msn icons, files and folders alike. After a few days, I've learned that this is not the right way to uninstall msn!!! But it is already too late... I can't uninstall it through the control panel because all the files have been deleted. I urgently need to uninstall msn because there is this error which unables me to log on and use the messenger so I have to reinstall it.
The msn messenger still pops up every time I opened my laptop but I can't use it so I have to uninstall it.

HELP!!
