DooM 3 problem

[Palomino]

Hi guys,
I have installed doom 3 and I have tried to run the timedemo, but appeares this problem:

]timedemo demo1 usecache
--------- Game Map Shutdown ----------
--------------------------------------
WARNING: Couldn't load gui: 'guis/map/loading.gui'
couldn't open demos/demo1.demo
--------- Game Map Shutdown ----------
--------------------------------------
--------- Game Map Shutdown ----------
--------------------------------------

The timedemo doesn't run.
In doom 3's directories there aren't guis with this name.
What is the solution?

Fedora core 3 kernel 2.6.9
nVidia driver 66.29

EDIT: As video card: Creative Labs Titanium Ti4800

Sounds like the install is screwed up, some missing or corrupt .pk4 files.
