I installed the Battlefield 2 Demo and the Nvidia drivers that came with it because mine were older. Then, when I tried to start Chronicles of Riddick, I got an error saying I needed support for OpenGL 1.3 even though I could play it before with my 6800GT. Next, I tried to get the newest drivers from the Nvidia site and installed them after using Driver Cleaner. Now, I still get the same error message.
