Effectively hamluis's idea, I would try installing Moo0 System Monitor, then rebooting, and then uninstalling it.
The hope is that installing it fixes it (because the error you are having is usually due to an incorrect or incomplete uninstall in the past, such as from a partially failed uninstall, or a user simply deleting program files instead of uninstalling properly). So installing it repairs the missing stuff.
Rebooting is to make sure it's fully installed before uninstalling (to complete the fix).
And uninstalling is just for because you don't even want the program, and ideally this time it uninstalls it fully and correctly.
