Hi,
I'm on macOS High Sierra v. 10.13.2. Since the update to ADE 4.5.7 (4.5.7.179634), all the images have disappeared in some PDF with DRM, and now appears instead a kind of black and white blizzard of snow, like parasite dots on a TV screen without signal. I often have to refer to those books (which I have bought!), but without image, they are mostly unusable. Very frustrating, since ADE is the only app that can access to those DRM eBooks.
Is there a way to fix this issue?
