This happened to me too, and after reading someone's answer regarding the amplifier, I saw some light. I have 2 standard non recording Boxes and since last Friday's storm, I was stuck with the channel that I left on Thursday, I tried the menu option and the error appeared and couldn't connect to the X11 platform. I searched for the Amplifier/Splitter which I belive was really old, replaced it and voila! Everything worked just fine. I know that it may be frustrating for some people to have their new cable set up and not working afterwards, but you must understand that sometimes the hardware issues are in place, and is not a bad Comcast service, but there are so many variables on today's connections, that is not easy to troubleshoot so quickly. Hope this Helps!
