Since I could not open any ebooks on Adobe Digital Editions due to the error message "E_ADEPT_INTERNAL", I looked online what to do when you get such an error message. I tried to follow the instructions there, however after entering my password the program said "Deauthorization not possible. Try again later". After failing at that attempt, I uninstalled and reinstalled the program in the hopes that now it would be working. When I reinstalled the program, it did not even ask me to enter my Adobe ID again, so I am facing the same problem again. What can I do to get the program back to work? Thanks in advance!
