or is there a 13 gig patch to download?

I have the same thing, its still trying to download.
What did you do to stop it?

[Ishmael]

To stop it, open steam and go to the games library. My memory is a little hazy here, but there should be a bar down the bottom saying "1 item downloading," which you can click on to expand and then press pause on the bottom right. Alternatively, right click on the game name and click "pause updating." Then, right click on the game, select properties, go to the updates tab, and select "do not update automatically."

Of course, you've probably figured it out by now, but this might help somebody else for future reference or something .
