It appears the search path is wrong. I would expect it to look in D:\Program Files\Lucas Arts\Star Wars JK II Jedi Outcast\GameData\base for the pk3 files (which is where I believe they are found). You can either move the pk3 files out to the directory it's searching or add +set fs_basepath "D:\Program Files\Lucas Arts\Star Wars JK II Jedi Outcase\GameData\base\" to your startup.

"No, Mr. Bond, I expect you to DIE."
