Can't get cs working, please help!

[KillaBong]

The game is on my computer fine, but when i try to connect to a server it doesn't work right. It connects to the server i want, then says server build# or something and just counts down to zero. I don't know why it's not connecting to servers correctly, but any help would by good.

Try updating it. Is this 1.5 or 1.6?
