Still, can you try each script on its own..without any of the others running? This to rule out scripts interfering eachother. You can easily turn them off in Plus! Preferences, simply uncheck the box infront of the script(s).

If they do work separate you turn on the scripts one by one and check if it's still working ok.

I know Swimming Personal Message (i've got it here and used it to see if it worked), but since you uninstalled that script it shouldn't cause you any trouble. You could check if the folder of Swimming PSM got removed from Scripts folder (C:\Program Files\Messenger Plus! Live\Scripts).
