so because the 7epg has ended its free period i downloaded big screen epg but for some reason could not download epg for a few channels so i deleted the mcepgXXX.xml file under \windows\ehome.
when restarted and reloaded 7mc it could not download an epg for christchurch (8025) nor any other postcode i plugged in. ok so set up tuner, but after scanning 100% three times it couldnt find any channels!
what have i done??
