Last update doesn't work – Canon Lenses Review

It just crashes on startup. The previous version worked fine. I've tried to fix this by deleting and download the app again but it doesn't work either. Please include more images of every lenses. Different angles of view would be nice. Maybe many users are familiar with the different technical issues of each lens. But it would be a plus to include a section of common concepts like focal length, aperture, minimum focal distance, EF vs EF-S mounts, etc.
