Help with Windows Live Messenger?

Your invitation was not sent because you need the latest version of Messenger to use the Application Sharing feature. Please go to the Windows Live Messenger update site to install the latest version.

I keep downloading the latest one ( I think, because I have 8.1) but this messege keeps coming up. What the heck?
