Game will not Start

I just downloaded the game and the Source SDK Base 2007. After it was done installing, I tried to start the game, but a message popped up saying, “The registry is in use by another process, timeout expired” Can someone tell me how to fix this?

Exit Steam and restart.

Nope, still getting the message.

I faintly recall getting the same error once, but I think it resolved itself by rebooting the computer/restarting Steam. In any case, I found these links in my bookmarks that seem related, perhaps they might help you:

Oh, yes, I was able to run it after re-starting steam. It didn’t work the first time for some reason, I must have not turned it off all the way. Thanks for the help.
