Apc40/traktor scratch duo

Soooo ... I would like to get traktor working with my apc40..

I have read various threads... downloaded various tsi files... tried following the steps (to the best of my ability) and still nothing! In the device drop down there is a selection for the apc40 however nothing appears when clicked (stays empty in all fields) and i did attempt dumb mode, followed those steps, and nothing seems to be working !!

Should I use the audio 4 dj or is my fast track ultra just fine? (maybe that's my issue)

I'm running it off my pc desktop computer (studio computer) not a laptop !

If anyone experienced something similar and can help out, would be much appreciated !

Sincerely,

The Beatz
