Game not launching completely

[bigdeckdav]

As I launch the game, it enters full screen and stops loading and stays on a black screen. When looking at the bootstrapper it shows "Unknown command: "resetCustomGametype"". I fixed this last time I played by un-overclocking my gpu, except this time it is already un-overclocked and the error is back. My drivers are up to date and am unsure how to fix the issue. Help?

Type r_fullscreen 0; vid_restart into the bootstrapper cmd window. Ignore the unknown command warnings, they do not mean anything.
