I went onto the Nvidia site and downloaded what I thought to be the latest drivers for my 9400M (I have the 13" Unibody Macbook Pro). Unfortunately after restarting my computer the screen has gone to a wonky resolution and the colors look like something out of a DOS game. I can't find my Leopard Disk that has the drivers on it, does anyone have any suggestions on how to revert to my old drivers (there was no backup on the hard drive)?
