I have a customer with a 500 that we just updated from 2.69 to 2.76a. They have a few pots lines on a 8trk card in the 2nd cabinet. Since the upgrade we can't get CID to work on any of the pots lines. We are getting CID on the PRI. We have a RCM2 on the SCP2 card on OP3. We are also having a problem getting easyset to work since the upgrade but that might not be related.
