I can't get this to work on Win10

I go to Channel Groups --> All Channel ---> I can see all my channels and their logos

When I click on a channel there are no programs listed

 Something isn't matching up with the xmltv file.

What do you get in the Full EPG section?
That should have all the channels in the xmltv file regardless of whether there is a stream in the m3u.

Turn the Debug menu on and do a NUKE or Service if you think the xmltv ids match the m3u tvg-ids.
