I do also have the same crash issues. But understanding the pattern is not obvious. Here are the following steps I have followed.
I do have a XP media center edition, SP3.
Intel® Core™2 CPU
T5600 @ 1,83 GHz
1,83 Ghz 2,00 GO of RAM
ATI Mobility Radeon X1600
I installed the game (not under an admin cession, so I had to specifically run the installer as admin).
The game crashed when pressing the “fight!” button.
I rebooted my competer an opened an admin cession.
The game ran smoothly. But I lost the battle. Damned.
I played a bit with the options (screen resolution, full screen, removed the motion blur, which I didn’t like). The game crashed on fight.
I have trying to go back to previous set up. (except motion blur) The game crashed on fight.
I uninstalled - reinstalled (I was still under admin cession)
I noticed that my previous option selection had not restaured to the original (motion blur was off.
The game crashed with all options on or off.
Rebooted under user account.
removed all options. Game crahsed
With option removed, reduced resoltion, and played without full screen.
It worked !
Full resolution and not full screen. It crashed.
