Hi Pickles !
You wanna uninstall Tooltips now or fix it ? I don`t use it, so I can`t help you with the langauges settings.
If you wanna uninstall it, try control panel add/remove software, or an uninstaller in the propam-folder of Tooltips ?
Or click "Start", choose "run", type msconfig and check the systemstarts, maybe disable Tooltips there.
