If you are planning to go this route,. If you don't know how to backup a registry entry, Google it... I'm not spoonfeeding those who wish to be lazy. Also note that you are doing thisand I am not to be held responsible for any damage caused to your game.To do this on Windows 7, 8/8.1 or 10 (can't speak for other versions of Windows as it's been awhile, sorry. Google's your friend.), press Start, type 'regedit', navigate to '', collapse that menu and simply right click and delete everything for the expansion you wish to uninstall. Then start your game and it should be running fine.As a visual aid, let's just say I uninstalled Seasons and I wanted to remove the registry key. I would simply just right click and delete the entire entry, like in this image.
