I have exactly the same problem. Game Cache verified.
But how do you disable autosave in the console?
By the way, enabling the console is an interesting experience. There are line upon line with errors and warning saying "Fix this, or you will experience a crash". I will try to get a screen shot one of these days if I can be bothered.
I payed only $2.50 for this game (new retail, in store), and I think I know why I could do that...
