The resolution list is provided by your graphics drivers normally, so the only way to add or remove them is via the driver configuration, your best bet is to google that as I'm not sure how you would do it. But the method for the fix is right, in the main menu, change the resolution to any 4:3, 16:10 or 16:9 aspect ratio resolution, then start or load a game, once your in, change it back.
