@ N24Reporter:
I'm using Windows XP. I only have the option of selecting DX9. An error message appears after I launched the game but the intro keeps on playing if I don't click ok on the error window. It then turns to a black screen after the intro is finished.
I tried updating the video drivers and changing the account name, since many reported that having accentuated characters in it (é, è, ö, ä...) caused the crash.
