Reply to Xone 1d midi help!!!!!!

Hi guys,

I've been using the Xone 1Ds for quite a while and I'm pretty happy with my controllers. I recently moved and changed a litle bit my setup. I used to connect the 2 Xone 1D's via USB HUB and I was playing with traktor. Now I use only 1 Xone 1D but Traktor does not receives the midi messages. I'm connecting the unit directly to the computer via usb cable. I've downloaded the latest driver (uninstalled previous one and installed the new one- again) restarted my laptop (mac), restarted Traktor. but nothing changes.
Xone 1D is visible in the Audio Midi setup window and it is not gray, but when in traktor... the little dot on the top of the screen indicating the midi reception is not indication anything.
Please help me .......
Thank you
