Until recently I was able to download ebooks from the public library and open in digital editions. Recently changes were made through the library's overdrive system and I could no longer open books in digital editions. I was advised to update digital editions and de-authorize the old digital editions. BUT my old adobe account is attached to an email account I can no longer access. And I do not have the password for the old adobe account which would allow me to de-authorize it. I opened a new adobe account but this did not resolve the issue.
