WELL I installed it, and now I can't uninstall. But I gave it to my friend, and he uninstalled it fine.
Well there's a lesson learned - don't install anything if you don't fully understand how it works or how to get rid of it. It's best to have a complete system backup before installing any transformation pack which modifies system files.
Sorry I didn't see your first post earlier, I would have advised you not to install it, but at least you got it fixed thanks to your friend.
