Reply to Twitch - TP2 Help

Hi guys, after having a Twitch for a while and not using it much I decided to give Traktor a spin instead of Itch but i'm having an issue with it running on my mac, 13" I7 10.8.2.

The issue is as soon as I select my Twitch in audio setup all the lights on the twitch turn off and nothing happens, if I unplug then replug it the touchstrips light up but it won't connect until I restart my mac.

Works fine every time in Itch though.

Any help appreciated!
