Just cause was unable to start. Please make sure that you have installed the latest drivers for your graphic card and directx. in addition, please make sure that your graphic card supports the functions vertex shader 1.1 and pixel shader 1.1

I think I ran across that problem when I installed JC with Vista. Make sure your video card is updated and re-install JC.
