How do you fix Normadie in NFS Porsche unleashed

the problem is it keeps freezing or the game shuts down to the desktop isn't it? "yes" well you are probablyusing a nVida graphics card and for some unknown reason the card conflicts with the sky files for normandie to fix this go into my computer double click on "local dick (C)" (if C is not your default hard drive then you will have to substitute C for your drives letter) then go to "program files" , need for speed, Porsche unleashed, game data, sky. you will see 2 files called "Farmland" and 1 called "Farmland.fsh" these are the problem now first lets copy the "canyon" files and then paste them down the bottom of the folder then rename the "farmland" to "farmland.old" now get the copied files of "canyon" and rename them to "farmland" now exit the window and open Porsche and race on normandie note: this does work i did it and it works brilliantly
