Well first I recommend you go to MegaGames and go to the left side of the site.
There will be some categories.Go to patches/mods and click on J.
You will find Jedi outcast near the middle.
Go to patches in jedi outcast on megagames and get the 1.04 patch.
for more more information go to jkfiles.
They have mods if you want them.
All mods have a redme file with instructions to install a mod.
Hope you like all this info and good luck with the problem!
