Been doing this last few days. Restart fixed it yesterday but not today. Just have data populated on the the Non-USA channels. There are a few of the FoxSports and the local CBS/ABC/NBC/FOX populated as well.
I went ahead an deleted the EPG.db files but didn't delete the epg_xmltv.xml file in my Database and that fixed everything.
Anyone in this thread that needs help, let me know. I knew about deleting those files but just wanted to make sure. Things change weekly and sometimes daily so wanted to hear from psycon.
