Cablecard Issues


I am having issues getting my Cablecard properly activated (validated).  I have been on several calls with the CSR's that continue to tell me that the "cablecard is bad" and that I need to go to the Xfinity store to get a new one (now on my 3rd CC). This device/setup was working perfectly at my old address.  All other boxes and internet are working flawlessly.  My setup details are below.  Any help here is appreciated.
