Im having trouble with the game now, it was working since the first install but now since i chagned the settings to lower graphics to remedy the stuttering and low fps the game loads fine but when I try to race I get booted to desktop. I've tried all graphics settings nothing seems to work, I'm a bit stumped.
I had this issue... spent 2 hrs trying to fix it... delete the graphic settings file located in the NFS Shift folder under the your my documents folder, its an XML all by itself. Next time you run the game GFX settings will be back to default.
