I'm not sure that you can only have the uninstaller to remove something from the registry (if that's what you want to do). Instead install the game once more in the exactly the same directory it was before, and run a registry cleaner. A registry cleaner is a small program that removes double copies or nonexistant entries in your registry. That should do the trick...

I don't know of a good registry cleaner that I can recommend. I know that there is a free program called RegClean used for those purposes. Search the net, there is a ton of useful freeware out there.

Also it's not wise to leave your e-mail address on a public forum. Now anybody can send spam if he or she wishes it. This forum has private messaging and you should use that prior to giving out your e-mail to total strangers. This way you'll know who spams you...
