I purchased an ebook back in 2008, it was a huge volume to learn a foreign language vocabulary. I had been using this book for 10 years without any problems on my Macbook and iPhone. Recently though (after I updated ADE) my Macbook refused to authorize it and requested a Vendor ID. Current Adobe ID does not work. When I first purchased the book and authorized it on my computer I used a different email address which I had to change later on because the email service provider just shut down, I no longer have access to it. I had no problems using the ebook though even after the email change until the recent ADE update. Is there a way to solve the problem?
