One more thing to add:
This problem could be caused by the Handwriting plugin!
Firstly do what CookieRevised suggested to fix your installs
Then uninstall the Handwriting Plugin:
- close all instances of MSN Messenger and Windows Messenger completely,
- delete the file MsnHandWriting.dll from your Messenger Plus! Plugins directory
(default directory is: c:\program files\messenger plus!3\plugins).
- Go to add/remove programs in the software tab in your configuration settings.
Look for "Ink Redistributables" or "InfoPen", if existing, click it and uninstall it.
