I recently upgraded my laptop to one from the same vendor so all I had to do was to upgrade a few drivers on the hard drive. Unfortunately my copy of ADE is not so cooperative. Every time I try to download an e-book I get the message "E_AUTH_BAD_DEVICE_KEY_OR_PKCS12". Uninstalling ADE (all three versions) along with cleaning the registry does not clear the error. And I cannot de-authorize and reauthorize my new laptop as the de-authorize option is greyed out. Anyone else encounter this issue?
I have a similar issue. I've been waiting for an hour for Adobe 'Support' to get back to me on chat. I hope they are well!
