Reply to Fader missing on Traktor Pro 2 with NI Audio 2 DJ

I just purchase the Native Instruments Audio 2 DJ sound card to be able to get the sound out from Traktor Pro 2 from laptop out to other mixer, etc. I notice that when I plug the Audio 2 DJ unit into my laptop via usb, Traktor Pro 2's fader on the mixer is missing. But if I unplug the Audio 2 unit, then the fader on the mixer comes back on when the TP2 is running by itself. Have you had this problem? Any suggestion to this? If not, is there a way to uninstall and reinstall Traktor Pro 2 without loosing all of my cue points that I have spent so many hours prepping for? Thank you in advance for all of your response.


I am currently running Traktor 2.1.2 with MacBook Pro 15".
