Reply to Issues With TA2 distorted sound/ freeze

I recently upgraded to traktor pro 2 and while i was using the sound card on my omni control everything worked fine. I decided to purchase the Traktor Audio 2 interface to get better sound. It actually gave me distorted sound for about 5 seconds before it freezes up Traktor pro 2 (the software). This is my connection: Laptop -usb-TA2-channel A connected to speakers.
Laptop -usb- Omni control (controller) and i have my headphones connected to channel B.
I notice channel A LED flickers while its trying to play doesn't stay a solid green all the time.
I have updated all the drivers and software and restarted as well. Also im running my laptop with windows 7, i7 q 1.73gh, 8 gb of ram. Can anyone help?
