Reply to recording w/Audacity from DJM-900Nexus .. troubleshooting w/screenshots.. plz help!

hey everybody! i'm finally about ready to record my official club promotional mix, and was having a little difficulty getting the recording to work in Audacity..

I went ahead and took screenshots of the 5 "critical" settings screens that I believe may be of most importance (at least the screens that any online tutorials directed me towards)

these were the only 2 tutorials i was able to come across online that were related to recording from a DJM-900nexus to Audacity.. one of them directed towards the DJM-900nexus.. found here:



and the other one was basically a Pioneer guide to recording on the DJM-2000nexus (they said the steps were the same, but still not working..) found here:





I went ahead and attached screenshots from my DJM-900Nexus Setting Utility and preferences windows of Audacity..

NOTE: I am using all digital outputs, so I have all my DJM-900 knobs set on "DIGITAL" (vs. CD/LINE, PHONO, USB).. ALSO, I am currently only using Channel's 2 & 3.. I have a USB cable going from my DJM-900Nexus into my MacBook Pro..

Are there any certain settings that I have set wrong on my computer end? And also, is there any further configuration that I have to physically do on the mixer end? Please let me know, thanks for all your help guys!! I'll be sure to post my promo mix as soon as I can get this working
