I've uninstalled DE and reinstalled 4.5.10 after all the usual tricks (like returning a book, deleting the .acm file, etc..) failed.
I can't read any ebook - period.
The program is now completely useless to me, and obviously, to other Windows 10 users.
It needs to be fixed - or my library needs to switch to a digital reader that actually works with the latest version of Windows.
