Hello, I have several HT1000 units and a licensed copy of the RSS. My RIB unit recently failed and I purchased a REBLESS unit online. The RIBLESS unit works, I verified with reading the plugs from my XTS units. When I try to read the HT unit the software uses com1 (correct) and runs as it is reading the code plug. Then I receive a message that there was an error. What am I missing here ?? Thank you - Jon
