Reply to traktor pro 2 and typhoon

Hey there

Im sure someone has asked this and received the answer i just cant find the answer.

I recently bought myself a vestax typhoon and I have a version of traktor pro 2 that is installed on my macbook pro.

I have installed the TSI files from the vestax site and traktor does respond once i imported the TSI however.... When i change my audio outout to use the Tyhoons sooundcard and not the internal one... the cross fader and volume bars control does not appear on the interface and is unresponsive....

What do i have to do

please help
