Hey.
I have bought Half Life 2.
There is with Half Life 2 an Counter Strike Source as multiplayer game.
I have updated it with Steam and decrypt it and everything to play it.
I talking about CS:Source :P
But when i wanna play offline with bots it says
"The game is not yet ready to play offline". 
But Half Life 2 is everything allright.
I dont know whats up with this problem.
Can someone help me ?
I have original if someone have problems to me.
