Cant open game while SRCDS is running.

Hello!

I got a problem, when im runing my server, i cant open the game, i cant close my steam, and the friends stats stuck in "Playing Left 4 Dead 2"
Looks like the steam thinks the srcds is the game client.

Is there a way to "unlink" both?
Tired to killing Steam process just to play, or even open the game.

Note: Steam and the server runs in different folder, in fact the server runs from another drive.
Thanks!
