Somethings wrong with the screen
 

See i just got this game yesterday on steam, and when it finished downloading it i started it up and the screen was zoomed in. I don't know why i tried cg_fov it did nothing. I can't realy explain much about the problem. I don't know too much about computers is their something i have to do in the jampconfig i have no idea please help.

it could just be your screen resolution.
did you try looking under the "setup" tab on the main menu? there should be an option there about "video mode". change that to a lower setting (like maybe 800x600 or even 640x400).
hope that helps.
