Help, i can't play L4D2

[.rea]

Hi guys, i've got a problem with L4D2. When i press the "play" button, on my library, L4D doesn't start. There is a message that say "This game is not available. Try later"

I've restarted Steam and reinstalled L4D2 but it didn't start.

There is someone than can help me?!?

First of all, verify integrity of game cache. Delete clientregistry.blob from Steam's folder while Steam is not running. If it doesnt work then check if you have newest version of visual c++ 2008 redistributable installed for your system.
