DJM-450 and Traktor Pro 3

Needing some assistance getting a DJM-450 connected to the Traktor Pro 3 software so I can use the external mixer to control the Traktor software and record a mix on the computer.

I can only hear audio from Traktor when choosing Komplete ASIO Audio Driver in the Audio Setup section of Traktor.  When I choose the DJM-450 ASIO driver and setup output routing, I see signal on both channels of the mixer but no sound comes back out of the computer.  In the Traktor Pro software I have tried several different combinations of settings under Audio Setup, Output Routing, and Input routing with no luck so far.  Any help you can provide is very much appreciated.

Thanks,

-Greg
