I'm using a traktor kontrol s2 mk1 with traktor pro 3 on a macbook pro. Ran the setup wizard and it seems to recognize the device. I can use the browse wheel on the s2 to load tracks into both decks, but I can't get the song to play. All that happens in traktor pro is the "cue" button flashes. I've tried reinstalling the traktor pro 3 software as well as the native access app. I tried running the device updater but it says my firmware is up to date. I even downloaded traktor pro 3 to a different computer (PC) and it's doing the same thing there.
