Suddenly I could not download books. I got the above code. I tried to follow the advice to take away the authorization but I cannot. I have taken away the program/app and downloaded it again. I think the problem is that my default account is connected to an emailadress that was taken away permanently about one week ago. In my account on the Adobe homesite I have changed my email to the new one but it doesn´t help. My husband had about the same problem with his Eurosport subscription and he had to get help because of a moment 22 situation.
