JustZoB, are you extracting the archive? There should be a file named "Sword and Sorcery 3.h5m" in the Maps folder. It should be visible in both version 3.0 and 3.1, but nothing will work in version 3.0.
You can check if the map editor can open the map. I don't know what that will achieve, but it's just a suggestion. You can also try other maps. But it's best to just find a working version of the game.
