Hello
I had a very similar experience to yours. I contacted the firm that sold me the book (The Book Depository) who got back to me almost immediately. It seems that this is a known problem with ADE - and I have since found other users talking about it on the web. The message from the Book Depository suggested I look at
this thread on the Adobe Help forum.
For me, this did not work, as ADE does not seem to recognize the command Cmd/Shift/E, which is supposed to allow you to de-authorize the Book. However, this may have something to do with my using a French keyboard on a Mac. If you are on a PC you may get it to work.
Since then I have been looking into stripping the DRM; unfortunately I am unable to install any of the required programs. I am in a passage full of little twisty error messages, all the same.
