although I doubt it since people are ALWAYS playing when i look.
Are you absolutly sure you have the correct version? We're currently on 3.1.4, not just Beta3.0.
Make sure Windows Firewall isn't blocking the Source SDK Base (it does by default, I have to go and unblock it manually on my computer, or tell it not to block the first time I launch the game).
Check to make sure you have a file called "steam.ini" in your gesource folder. If not, that is your problem and I can guide you from there.
appID=218in there. That's all.
