I have downloaded several regions and installed them to the Documents\Simcity4\Regions folder as stated in the instructions yet when I view them in game they show as the basic, flat "New Region". This is on a fresh install from Steam on Windows 10. I have had success with these exact maps on an old Windows XP Disc version. I don't understand why they aren't working on this version. This is happening with every region I have added and I'm only using Complete Regions found on this site.
