Started about two weeks ago. When scrolling out beyond 48 hours I get a message saying the guide information needs refreshing. I click OK and and after the 5 minute wait all if fine. One or two days later I get the same message. After the 4th time I unplugged the 722 and rebooted it that way. Made no difference. I'm waiting for the reboot as I write this. The same thing happened 6 months ago and after 4 or 5 cold reboots the problem went away. Perhaps one of the Dish reps here can suggest something. the 722 is 3 years old and this is the only problem I've had. Thanks.
