Suddenly missing all channels below 440
Hello everyone. This morning everything was fine. Same computer, same brower, same everything. This evening every channel below 440 is missing. I'm on the "All Channels" programming grid page.
If I use the search field to search for ABC (usually channel 7), CBS (2), etc, I can get the channel, but it's a high number (ABC is channel 1007, for example).
Does anyone know what might be going on?
