When I try to open library e-books in blue fire reader (which demands loging in to my adobe id ) on my iPhone 5s the log in doesn't work and a pop up about Read Mill shows. I used Read Mills app for ebooks before they closed down. The blue fire support says that this error is caused by the ReadMill information in my Adobe Account. Due to ReadMill going out of business, Adobe no longer recognizes these accounts as valid. How can I remove the ReadMill portion of my Adobe Account?
