The ID that matters is the internal ID, that stays the same with the account even when the email or password changes.
Instructions to find that internal ID below.
You can find the internal ID registered to ADE at the moment using crel-shift-I to see if that matches.
(ADE1.7.2 only gives the external id, not the internal one. One of the very few areas ADE2.0 is better)
One thing that might be worth doing is deauthorizing both ADE and the Sony, then reauthorizing.
The authorization sometimes gets its knickers in a twist.
ctrl-shift-D to deauthorize ade
ctrl-shift-E to deauthorize the Sony (to ADE with Sony plugged in)
OK. To find the internal AdobeID.
open a sample DRM .epub file as a .zip file.
With some zip programs, you can just open the .epub as an archive (ev, with 7zip),
with others you will have to rename the .epub file to a .zip file first, then open it.
find the file 'rights.xml' within the zip. Probably 'META-INF\rights.xml'
open the rights.xml file
inside you will find a section '<user>' that looks something like
That string is the internal version for your AdobeID.
That stays fixed for the AdobeID, even if you change the associated email (or password),
that internal ID is what is really associated with the book.
(n.b. there is no point in trying to change the urn to a current one you might find and recreating the .epub file; the DRM is cleverer than that).
Thanks very interesting and helpful.
I checked the reader and 2 eBooks.
As expected the ID of the reader is different. But also the ID's of the 2 eBooks.
... and I'm not aware that I ever had another Adobe ID.
ME too..... Only adobe customer services is meant to be resetting my email and password.... They promised 3 days and I have not heard back. I hate that it's a labirynth on here to get hold of them. I am considering blogging how bad this whole thing is... And you tubing people to warn them about digital editions being the most difficult Ebola to own. You risk not getting what you pay for.... Ie your id opens the book and when something goes wrong... You are on your own
