It is possible that your non-standard installation location is the problem - perhaps all of the ED data was not installed because of that, or ED cannot find it.
Look inside your ArchiCAD program folder > Add-Ons > EcoDesigner. You should see the attached. The usage info and more is stored in one of the localized folders. If they are all there, and each folder has 6 XML files in it, then EcoDesigner may have an issue with finding those folders if AC has not been installed in the standard location.
