Yes, it looks like when the program guide service was broken a couple years ago.
I agree that it looks like a server side issue and not anything we can fix ourselves.
I will also submit a support request, but I am not optimistic since other threads have noted a lack of response from support on other issues.
I hope we get what we paid for, since as I noted earlier, North American guide updates are still being sold on their site and so they must be supported.
