In Aug we spent HOURS online with Xfinity regarding this problem. They said it was HBO's problem. They gave us a phone number to call HBO in NY, their corporate offices. No help there. My husband found a phone number to contact HBO, they said it was Xfinity's problem. We cancelled HBO out of frustration. Today is the last day of the $11.99 a month for a year. So we thought we would try again. After 2 hours chatting with Xfinity online and via multiple call backs, we were about to cancel and just buy it from HBO directly. As a last ditch effort, my husband rebooted his computer, and VOILA! It is now working! We had to reboot each device, but at long last we have a resolution. Hope this helps!!
