Getting the game to work without Steam!

[Anvilfolk]

I'm pretty sure you're better off asking these questions over on Steam Support - it's not related to CoD at all, it seems.

That might happen if you have an unstable internet connection. I've had Steam break on me once, and I've been using it almost since it was out. Generally, I find it works pretty nicely, and it's been on a few of my computers.
