Have you tried to open and save one of the images yet? As I mentioned before, something's wrong with the maker notes. Saving the images again might correct this problem.
If I open and save one of the image with an another product, there will bo no error in ImageEN.
The problem is that my Application has been distributed to many users and I can't tell them to save theirs pictures with an another software if they own a FujiFilm cam.
