I'm using a German ADE version installed on my desktop computer via a download from the German library I use.
Initially I was able to use ADE to download and read e-books from the library, but now I get an error message telling me that I need to reauthorize ADE via "help" -> "reauthorize". However, the option "reauthorize" is not activated.
Help pages tell me I first need to deauthorize - but there is no deauthorization option.
Does anyone have an idea? I had this problem earlier, but our librarians were not very helpful either.
By the way - I'm highly annoyed - my library pays for books that are not actually available to me. And I now need to invest time and ask for the kindness of strangers to spare their time for this issue ...
