I cannot download any books to Adobe Digital Editions because I keep getting the above error message. I think it is because the e-mail address associated with Adobe is an old e-mail address. But I cannot change to my new address because I do not know the Adobe ID number associated with that old e-mail address. Also, I cannot use the "forgot password" because the e-mail from Adobe with my old password will be sent to the old e-mail address that is defunct. Does anyone know how I can get around this issue?
