EOC - Crashes to desktop when starting a game

Just bought I-War 2 today, installed it, patched it to 14.6, and whenever i try to start a game (be it single player campaign, instant action or a MP game), i see the loading bar for just a fragment of a second before it crashes with an error message about loader.exe and dx7graph.dll . Intro videos and Main Menu work fine, but it's junked past them.
Here's my flux log , just in case, but it hasn't helped me finding the cause.
And before you say it, i did use the search function , but none of the results helped me.

Quick HW specs, if needed:
Athlon XP2400+
512 Ram DDR
Radeon 9600 Pro on Omega drivers 3.8 (the one based on Catalyst 6.3)
MB: ECS K7S5AL
Sound: Terratec Aureon 5.1 Fun
Windows XP SP2 (French, and my copy of IW2 is also in french)

Please help me, i don't want this game already collecting dust the day i buy it
