Somehow my custom landscape transferred from Sky Safari 5 to 6 Pro on my Mac OSX. I am trying to update it given trees have grown taller. I looked in the Horizons folder and the previous custom landscape "My Landscape" is not even in that folder. I spent a couple hours trying to find the file with no luck, so I am not sure where SkySafari 6 Pro is reading that file because it still shows in the app. I ask this because it would be easier to replace that file. When I try to import a new landscape file it says:
Add Panorama
The file "Future World Media
Observatory.png" does not contain a valid panorama.
Any advice?
