I recently downloaded The Dark Mod. It installed fine, allowed me to change video, sound, and control settings, even downloaded missions. When I attempted to start a mission for the first time the opening video played, the menus for buying equipment and picking skill level played, but the actual gameplay would not launch. This error reads with every mission I have attempted to start: 'Hips' not found for attachment position 'HIP_SHEATH_L' on ENTITY 'EMAN| . I have no idea what this means or what to do to fix it. Has anyone else run into this or have any advice?
