Advertisements I don't know if this is a common problem, but I couldn't find any solutions here after searching: I attempted to upgrade my internal HD, and when I reconnected everything, I could not get any cable channels at all. The info for both cable cards state "contact your cable provider for service" and that they're waiting for data. I called Comcast, and they were happy to send the activation code to each and to both cards, but that didn't do anything. The rep said her instructions said to pull and re-insert the cards, which I did one at a time, and then had her re-send the activation codes, but it still didn't help. Is there any way to get the cable cards working short of waiting for an appt with a technician to come here?? (And, BTW, the last thing I tried was inserting each of the two cards in Slot 1, which is reported here to regenerate the pairing keys and make things harder - but at that point I was just desparate!) Thanks, Dave.
