Steam is playing a Cruel, sick, joke on me.

OK, I went to launch CSS, it was launching and then it said "Steam has found a problem with your local game files. Steam will now re-acquire game files."

I need help. I've never encountered this before.

That happened to L4D when I tried launching it once. I just deleted and re-installed and it worked again.
