If the map folder is correct, e.g. the map folder is not located in a sub folder but directly in the root than it should be correct. Maybe it is worth to wait a few more days until a valid map chart is available or you could try a different map.
Can someone please help me. Every time I try to download a map from here I forget how I did it the previous time. When I follow the link it only wants me to download some software that I don't trust. Is there a way to go direct to the map files? Thanks
