I just downloaded adobe digital editions. When I go to download my library book and open it with the program I get a message "error check activation". Help I don't know what to do. Everything is authorized but I don't know how I correct the error.
Error check acctivation
No me deja desautorizar
For people still having problems to deauthorize, downgrade to ADE 3.0. It worked for me. Internet Archive has the installer on its database.
