Have registered Adobe Digital Edition as a user and email address of user is current. In my new Kobo reader with same email address it states in settings "not authorized with ADE." Have re-set the Kobo - still no change. Have tried to go into ADE to erase current email authorized address. Can't do the function to erase. Use ADE to access my library. Have checked my overdrive account as well. Called Kobo and got me to de-install Adobe 4.5 and go back to 3.0. Still - no sucess. How do I start all over and access my library using my adobe account?
