Reply to Problem with Vci-100se and Audio 4 Sound card

i decided to play with my vci and start DJing again.
i installed:

traktor pro 2 1.2.1 (R12125)
Audio 4 Sound Card with 3.1.0 drivers
vci-100se 1.3 firmwire
v3.6.4 mapping

on windows 7

i start up traktor and turn on the vci. everything is good. the mappings work fine and i can play music.
i hook up the NI Audio 4 sound card so i can use my headphones and that when i run into problems.

i can play music but the i am unable to use the vci. its like the mappings disappear and i am unable to use any of the controls.

i was able to use this setup with no problems with traktor pro 1 on my friends mac and on the laptop i am using now...but that was a long time ago. i havent tried using this with traktor pro 1 since.

i tried searching the threads but i can find anything on this.

what am i doing wrong and how can i fix this? im very noob at all this
any help would be greatly appreciated, thanks.
