I am having the exact same problem, and correcting the shortcut link as Darth_Linux suggested does not work. Wraith_3, did this solution work for you?

I managed to click around and start a new game, but the briefing screen also has no text. Here's how the command line is, maybe I have it wrong:
"C:\Program Files\LucasArts\Star Wars Jedi Knight Jedi Academy\JediAcademy.exe" "+set fs_game dfmod"
