If I click OK to close the error box the Address Marker and Color Schemes dropdowns are empty except for a line which says "joinNL". Any selection on that page produces the same error message. Eventually I can get to the following steps but when I click FINISH I get a new error message from "wagmp_map.js that markerColor has no properties.
I have uninstalled Google Maps, deleted the .dat file, restarted the computer, reinstalled the extension and still get the error.
Any help would be appreciated - would love to get this working!
