I am a FiOS cablecard customer who uses a Silicon Dust HD Homerun Prime and Windows Media Center. I have the same problem which suggests this is a cablecard-only issue with Verizon. I too have been on the phone a few times and got a new cablecard but the cablecard still reports that I need a subscription. The cable box I have still works. It is worth noting that this is affecting both of HBOs properties, HBO and Cinemax, all channels. The rest of my pay content has no problems. My last call ended abruptly and I was bumped out to the main menu. This has become frustrating. Before that, I tried sharing advice from here concerning the Val: data in the cablecard's Conditional Access section. As she was going through her steps of which I had been through 4 times already, I lost her. No call back yet which means another 10 minutes wading through that auto-attendant to be placed on hold for another 10. I will check back here for news and post results of my experience too. Good luck all.
