Ripping models from Call Of Juarez Gunslinger.

Does anybody know how to successfully do this using 3Ds max or ninja ripper? I’ve tried both 3Ds max did nothing when i pressed the hotkey to rip models but ninja ripper froze the game and repeatedly flashes portions of the screen for about 2 minutes before stopping, i found nothing in the output file i allocated, with both software. Can anybody tell me what i’m doing wrong/help me out?
