CZ just closes and returns to the desktop -1 reply

Hi, i have just installed condition zero and after loading the game and selecting the map etc, the game just closes. I am using a GeForce 4Ti, 384 mb ram, a p3 1 ghz, i have updated the drivers for my graphics card and direct x 9 as well. Please help.

I'm having the same issue. I have a Geforce 5700. I just upgraded from a 1.2amd to a AMD 2000xp. Worked fine before.
