Line 4 of your fresh settings file has this entry:

"config.epg.opentv=False"

I presume this would disable the in-built system EPG reader which reads the SKY EPG data. Try changing OpenTV EPG to "yes" in the EPG settings page.

The EPGRefresh plugin just tunes the box to the selected transponder at the selected time or at an interval. The plugin doesn't actually have any code to pull the EPG off the transmission.
