Hello. I bought the premium version. When i try to add to blender it doesn’t show up as an addon.
Do you know any solutions to this? Thanks a lot

OpenStreetMap does not sell software. So you bought some third party software package. Perhaps you could let us know what software you bought and we might be able to help you. But it is more likely that you will get an answer when you directly contact the company from which you bought the package.
