I use ADE on a PC, Windows 10, on a Tab, Android 6.0, and on a Galaxy S5, Android 5.0. Since 20.11.17 after a Windows 10 update on sunday I see only a white book with white pages after importing a DRM ebook. The import of none DRM books is ok on all devices. The Tolino App works also probably on all devices. I have only a problem with ADE. The ADE Service said the number of logged in devices is ok. What can I do. Thank you for helping
