i added the game and then went to the server list and this is what i got. I think it has to do with the game argument-command line but i am not sure....is there any help?
the game would be left 4 dead 2

Hello undeadninja2,

I have just tested against the PC release of L4D2 to verify that this is not an issue with their new DLC. Launching into a server from GT Lite is currently working for this game.

We don't support the mac version just yet.

Can you provide the following info so that I can help track down your issue?

1. Operating system name, and version (Example: Windows XP SP2, or Mac OSX 10.5.1). Please state the actual version number.
2. Mac users: Machine platform type (Intel or PowerPC).
3. GT Lite version number. This is located on "Help->About". This number will read similar to "1.2.0". Please state the actual version number.
4. How you got the game you are having issues with (Retail, Steam, other please specify).
5. If you are having a problem connecting to a server, please include the IP address, port, and if possible, version of the server.
