Issues with s2 and pro 2

I just got a traktor s2 mk2 but the audios been choppy and laggy. Ive intalled a shot ton of drivers all day and still no luck. I also played with the audio set up options and still no luck.



im running a 2.3 ghz dual core with 3 gb ram. The settings inside of traktors audio set up it is as follows.
Audio Device:Traktor S2 mk 2
Sample Rate: 48000hz ( i played around with all of the latency settings for the sample rates of 48000 and 44100)
Process Buffer: 64 samples (played with just about all of them)
USB buffer: 4ms (only tried 4 and 3)
Overall: 8.7 ms
Built In soundcard: Traktor s2 mk2
Multicore disabeld

Ive played with so many options and am just ready to give up, but i know the answer is out here somewhere.
