It is now working. Thanks anyway.
I am getting the same error message when I try to activate Digital Editions.
E_AUTH_FAILED http://adeactivate.adobe.com/adept/addsignindirect email@example.com. What do I need to do?
I have the same problem on my ebook. I try to create my account on the ebook, but it say "the AdobeID and the password doesn't match". We try with another mail adress, sometimes we have the error E_AUTH_FAILED...
On this website we can login, so the account is working...
