DJM900NXS - Work with Trakto DJ Studio 3.0?

Hey all,

Having an issue setting up the DJM900NXS with Traktor DJ Studi 3.0 as a USB midi controller.  Mixer connects with the OS fine, DJM utility can see the mixer fine, looks like Traktor even see's it as a MIDI interface, but for some reason Traktor does not detect any knob/fader movements.  Also does not seem to detect any movement with the learn option.

Anyone have any ideas?
