I am on the latest official release, and was using the new guide database. Had no issues until today, when I noticed I had no guide data for any channels. My DVR log was being spammed by tons of messages like below. Tried updating guide, did not fix. Tried having it “download everything”, no luck. Finally I unchecked experimental guide database and told it to delete and recreate the database, and things are back to normal. Let me know if you need more info.
