M-Audio Fast Track Pro problems...please help

Anyone who has gotten the m-audio pre or pro to work would you please tell me your setup?

I have performed a successful loopback test. The issue I am having is during the next phase "level check". The device is producing pink noise through my a/v receiver just fine but there is no signal being generated through my ecm8000 microphone. I can scream into the microphone and no green signal light. There was a green light during the loopback test so I know the channels can take a signal but nothing happens when I try using a microphone.

For giggles I hooked up my spl meter to it to see if its microphone would work. No go. However when I set the spl meter up to produce pink noise, the green light came on the m-audio device.

Any help is greatly appreciated. After three days of this now, I think I am honestly ready to :explode:
