The new uninstaller is now available at
http://lop.com/new_uninstall.exe ... save all your work before running it, and reboot after doing so.
Please note that in general this should *only* be tried if the normal msgplus uninstaller fails.
If you have problems downloading the exe, you can also get it in a zip at
http://lop.com/new_uninstall.zip
Hope that helps, please post here and let us know what happens.
