I've been using the Load Program Guide feature ever since it was introduced. However, in the last week, my program guide data is empty and I receive the "The program guide file is not valid, or does not contain any program information for channels in your channel list" message.
My overall HTPC setup hasn't changed in over a year. The recent changes are:
1. Updated to MC 20.0.131 (previous working version was 125)\
2. Updated the firmware on my HD Homerun Cable card for the June firmware update.
Can seem to find any way to solve the EPG guide problem.
