Reply to Midi Fighter with Hercules RMX controller

Hi, im a novice DJ and I was just wondering what are the necessary steps I would have to take to use my Hercules RMX controller with my midi fighter and Traktor? I have the mapping for the midi fighter with Traktor Pro and the mapping for the Hercules with Traktor howeverI still cant seem to get them to work (mainly the Hercules I believe because of the soundcard). Any help would be appreciated
