Wish i saw this earlier but thanks for replying. I sent mine in for repair ($30) and it's once again performing great.

All of a sudden my AT fader has stopped responding to volume up commands and it is also out of calibration. It is at 0 before i get a 1/3 of the way up. I've recalibrated over and over with the same results. My studio partner has an AT as well and his is working fine on my computer and in the same session. I'm hoping that I can get this taken care of by sending it in to you with an RMA number for service. Please advise.
