Do you have StuffPlug-NG installed?
If so does going to Plus > Preferences > StuffPlug-NG > Uncheck StuffPlug-NG then click OK. Does this resolve the problem? If you wish to continue to use StuffPlug after, uninstall it (Start > Control Panel > Add\Remove programs > StuffPlug-NG > Change\Remove). Then go and download the latest version from
www.stuffplug.com
If you do not have StuffPlug-NG, the above does not apply to you, and you may want to try this;
- Uninstall MSN Messenger (Start > Control Panel > Add\Remove programs > MSN Messenger > Change\Remove > Follow Uninstaller)
- Reboot your computer
- Download and install MSN Messenger again.
If you use XP, for the control panel to be displayed like I said you will have to "Switch to classic view" and some of the wording may be different on older versions of Windows.
