View Full Version : Steam won't start Black Ops Multiplayer.

11-12-2010, 08:22 PM
I downloaded and installed the game on the 9th and everything worked fine until today. When I try to start multiplayer now, the little steam box comes up saying it is starting the game, but then it closes and nothing happens. Single player and all my other games work fine. How can I fix this?

I have the same problem. I even re-installed the game, and multiplayer still won't start from the steam menu, shortcut, or directly from the directory.

Restart your pc after game crashing.

I had this same problem. I validated the game cache, and my multiplayer works now. Give it a try.

1. Click steam icon and go to Library.
2. Right click Black Ops-Multiplayer and go to Properties.
3. Click the Local Files tab.
4. Click Verify Integrity of Game Cache.

When it's done, your multiplayer should work (at least this fixed it for me). This is something that I think steam normally does during an update, but it doesn't on some windows platforms. More than likely Win7 systems settings. I blame steam for this oversight.
