Reply to Problem with Midi Controller

Hey, I know this isn't a technical support community , but I have tried everything I can believe of and this is the most knowledgeable community I know of.

I recently upgraded to XP x64, and after initially working for one run, Traktor 3 no longer accepts signals from my midi controller. The only thing I can believe of that I did between it working and now not working was installing Traktor pro, which I have now uninstalled. I know that:

• The Midi Controller works, Ive used it in other programs
• Traktor "see's" my midi controller, its using its inbuilt soundcard and its selectable in the MIDI IN and MIDI OUT section and the green MIDI light is aluminated.
  
  
• The TKS file I'm using works

The midi controller in question is a Numark Omni Control. Thanks for any help you guys can provide.
