From the magic of Google:
It basically means that the server couldn’t authenticate you with the steam authentication servers to make sure you’re using a legit version of the game. It could be that Steam is down, but more likely it is a transient glitch. Here are some tips to solve:
* Restart steam. Close the stream from the tray, and run your game again.
* Log out of steam, then log back in. Try your game again.
* Close steam. Go Program Files then find ClientRegistry.blob in your steam directory and delete it. Restart steam.
* Close steam. Then update your system clock and start up steam again.
If this doesn’t solve it, you should email steam / valve tech support, or go leave a post on their forums.
