Reply to S4 Problem

So I recently came up on an S4 on craigslist with a flight case and TP2 for 630$ and I've been trying to set it up but I can't get it to work right. I'm using my original TP2 that I had before I bought this because he didn't unregister his copy yet.

What I can't get to work is the cue button. My headphones only play the master output, but is effected by the cue mix and cue vol pots. In my output routing I have the output master set to 1: Output L and 2: Output R. In output monitor I have it set to 3: Monitor L and 4: Monitor R. What am I doing wrong? I've restarted my Mac, reinstalled the default .tsi, pretty much whatever I can believe of besides reinstalling Traktor. Is that what it comes down to? Also, in case anyone asks, I have the Audio device set to Kontrol S4.
