I posted this in the FAQ forum but it's a ghost town.

Since installing my new video card (nVidia GeForce 9800 GT), whenever I open Toribash is gives me this error:

NVIDIA display driver files from different (incompatible) versions of the driver have been detected.

NVIDIA OpenGL acceleration is disabled in order to maintain system stability.

To resolve this problem, update the NVIDIA display driver. The latest driver is available at www.nvidia.com.

Now, I have the newest drivers installed and I still get this message. The only time I don't get this is when I run it in 256-color mode, which makes it look terrible and run unplayably slow.

Also, when I close the game after running it in 256-color mode, I get the following output in stderr.txt:

failed to load texture data/textures//menu
Extensions for bump mapping unsupported

Unable to retrieve login information

Any help you folks can provide is much appreciated.

It's because basically, you should remove the previous versions of the updates and only install the last one. http://forums.nvidia.com/index.php?showtopic=59116#1.2
