Yep, the manual install should still contain the older setup, just don't run the updater for now
FYI I have confirmed EQ2Maps has pushed out a major overhaul. I've been working with the team to iron out a few remaining issues with plugin and reskinning support. I have a working file set with all previous FetishMaps functionality + the new POI filtering. A Fetish update will be issued as soon as these changes go live on EQ2Maps.
