Reply to Complete Noob in need of some HELP!

So my buddy has a set of Traktor Kontrol S2's and I'm trying to get them set up on a MacBook Pro with 10.6.8.
He has a legitimate copy of Traktor on his Mac but I'm trying to set it up on mine so I can use them when he is gone. I have Traktor Pro 2.5.0 installed and running but I cannot get the tables to do anything. I've tried installing/uninstalling the drivers and the program itself a few times. I can't seem to get the computer to recognize the table at all. The CTRL light does not light up when you move any of the knobs or sliders.
