I had exactly the same problem after installing W10 Home b2004 and then found that SpectraLayers Pro 6 wouldn’t load and just presented the eLicenser error. I went around in circles with the eLicenser and My Account for about an hour. So frustrating. I ended up uninstalling SpectraLayers Pro 6, the eLicenser and the updater. I then CC Cleaned the registry and re-installed SL6. It worked - well, so far it has.
