[USR-TC] TCM Error on E1 DSP ?

Having a problem. Trying to help someone out configuring a chassis, and I can't access a 30 channel DSP (E1 version) with my TCM. Here's the error: I click the lights at the top of the card. Click Configure->Programmed Settings, and get an error message that says "Error Opening Device Description File". Anyone have any suggestion, or the correct file I need to make it work? Thanks, Joel
