The two best suggestion I have would be to:1.
Find the folder where the game is installed at, then delete it.....2.
Delete all references of that program using a registry cleaner. A good one is http://www.eusing.com/free_registry_cleane...try_cleaner.htm
I may not explain it correctly, but when you delete, or try to delete a program and then afterwards go to the Windows Restore Point, if there is a problem....... you make the un-installation of that program worse.... and on top of that,, you load it on to your restored os.
Once you uninstall a program,,, NEVER go straight to the Restore Point that is built in Windows. you'll make things worse.
