Problems with Traktor Kontrol S4 MK2 and Cross on Mac

Downloaded and installed the mapping configuration for Traktor Kontrol S4 MK2 and loaded it up. However on the last two occasions Cross DJ 3.3.0 has not recognized it. I can load videos and audio via the software but none of the controller knobs respond or operate. Should I just delete the current mapping and re-install it? I did two restarts in my troubleshooting but still nothing.
