Solution:-MSN itself appears to be up right now. You can check at http://messenger.msn.com/status.aspx...

If it's a problem with corrupted dll files, you can fix it by running this application:

Unzip it, and double-click on the .bat file.

If that doesn't do it, you'll need to check your connection settings.

If you do not connect using a proxy (if this is your home machine and you set everything up yourself, you wouldn't have one and not know it) go to the Tools menu, select "Options", click on "Connection" on the left in the window that comes up, then click the "Advanced Settings" button. Uncheck all the boxes except for TCP. Close Messenger down, open it up again, and see if you can connect. If not, open up Internet Explorer (whether that's the browser you normally use or not) click on the Tools menu and select Internet Options. Uncheck "Use a proxy server for LAN" if it's checked and select "Automatically detect settings".
