Have you installed any add-ons? It may be that the add on cause some problems.

Even if you haven't, this may help you repair the installation by doing the
following. Going back to the website and download it again.
http://get.live.com/messenger/overview Click on it as if you were installing
it, say run, tell UAC to continue or enter the Administrator password if
necessary, Click on Repair, and that should repair the installation.

That should work.
