Help with Jedi Outcast, error keeps occuring

[Quall999]

I applied the version 1.03 patch to my Jedi Knight 2 game. Multiplayer seems to work fine, on and offline. but, whenever i click on "Single player Game" i get this error:

JK2: v1.02a win-x86 Mar 4 2002
Initialising zone memory .....
----- FS_Startup -----
ERROR: filename length > MAX_QPATH ( strlen(Program Files/LucasArts/Star Wars JK II Jedi Outcast/GameData/base/levelshots/) = 78)

It appears in the window that pops up right before the game starts. With the black background and yellow letters. Anyone have any idea what is wrong?
