After successfully downloading an ebook from my local library (as an ascm format), to my PC, I attempted to load and convert it into a epub to read it in Adobe Digital Editions. ADE gave me an error message that it could not download the book (which I already had) & said there was an error getting Liciense, Liciense Server, communications problem "E_AUTH_BAD_DEVICE_KEY_OR_PKCS12. Using Opera Browser as default, My computer is using Windows 8.1.
Adobe Digital Editions version 2.0.1.78765. (newly installed today). This version appears to work with older epub books in my library.
