I figured out how to get it working. SwordWielder If you're laptop is from Dell go the webiste and download the driver for it. If it's from a different company then do the same except go that company's site and get the driver. Install driver, restart, install Jedi Knight, and should work.
However one problem may occur. Whenever i turn on my laptop, about 2 minutes later my whole screen turns bright. not like you can turn the brightness on a laptop but like every "light" color gets magnified; like white. It gets really bright that sometimes it's hard to look at the screen. However if i open Jedi Knight the magnified brightness goes away.
