If you have Activity Manager installed in your computer, try to perform a re-install. This way you will attempt to fix the application's errors. Re-install the application, reboot the computer and then watch the behaviour of the application. If you still have the issue with the appearing error, go to Start > Run > msconfig and click on Startup. Locate the Activity Manager and then uncheck it. Reboot the computer again and the error should have disappeared.
