Reply to Difficulty setting it up [S2]

So I had my S2 running with traktor well on my old pc but just got a new laptop and it hasnt been working all that well.

Whenever I move the browse knob, it always moves by two, how do I change that? its incredibly annoying.

And when I press play on a track, they dont play, but when I hold cue, it plays, How can I get the songs to play?
