Maybe this should be a feature request, to be able to download protected ebooks. It's an Adobe ePub book. My library site lets you download a 1.8K file that downloads the actual book (extension is .acsm). I can do it on my PC. However, when I attempt to download from my edge, it won't work. I can find the file in my download directory; when I click (from the reader) to open the book, it says it's a protected book, do I want to add it to my library. If I say no, it stops. If I choose Yes, it attempts to download, then I get an error message: E_ADEPT_DOCUMENT_TYPE_UNKNOWN: <HTM
I can open it as a text file, but it's all tags and codes.

What might I be doing wrong, or do I have to wait for an update?
