How do I uninstall this? When I downloaded it, I didn't make a backup of my entire game which was stupid I suppose. Anyway I've tried deleting every single file and folder associated with this but it still shows up in the editor. I've uninstalled and reinstalled the game and the editor, I've tried to load every update and all kinds of save files but I just can't get rid of this no mater what I try.
