Far Cry graphical problems

I just got Far Cry on the PC. The thing is, when I get outside for the first time in the first level, nearly everything is black. Basically, the ground and the sea are just solid black. I tried installing the latest patch, 1.4, but when I try and run it it says "Error reading setup initialization file". Can someone tell me what's going on, and how to fix it?

Did you download the cumulative patch (180Mb) or the other 127Mb one? Also, are you running XP or Vista?

I ran the game without any patches on XP without problems, but in Vista, I can't set graphics any higher than low or I get a blue haze over the whole screen from the get-go.
