Game Closes on Menu Option Click

So when I start the game up and click on single player, multiplayer, options, etc., it instantly crashes and I have no idea what to do, I've played since the game first came out and it's still doing this, I saw one forum thread about deleting the contents of a certain folder, and the player having the issue just "owning it" whatever that means, didn't help at all, but since my windows updated nothing has worked with Sins except Dev mode, so if anyone has encountered this and fixed it or knows how please help!
