I am experiencing a bug.

Game crashes with a message: Directx Error: DDERR_SCENE_NOT_IN_SCENE.

It so far happened every time i started the game and in random places. First time after the intro (a minute of wandering around the city) second time in apartment during a training fight (after 10 minutes of running around) third time during the intro (when the title appeared)
I am very tolerant of bugs even crashes but thats too much...especially since there is no quicksave so i can't just jump back to game (heck. i don't even know how save points look in this game)

My system is:

Windows Xp SP3
2gb of ram
AMD 3200 (2ghz)
ATI 4850


any help will be appreciated.
