Traktor Audio 10 not recognised on MacBook

Hi there!

I got my Audio 10 some weeks ago and have massive problems with it. I'm using it with an MacBook Pro Mid 2010 (Lion)

Installed the driver and the interface was working as along as I deconnect it. Afterwards I don't get it working again. Only a reboot is helping once.

I posted already at the NI forums and contacted the support, but they are not helpful nor very responsible. Got a mail, I should reboot.. Ha. Very funny. Now I'm waiting since 2 weeks for a response..

it seems I'm not the only one, so maybe some one has an idea to get it working..

Actual FW is installed, latest driver.

Many thanks in advance!
