Hi Jeff,
Yes, my laptop is authorised so it says. But I do not have acces to my old account. I have a empty account in an englisch version. My old account was a dutch version. My old laptop is broke and I have no acces to it anymore.
Adobe digital editions claims that I have acces to my books from any computer. But my new laptop has no acces to my old account.
My oldest son said he had the same problem when he started using his new laptop. He also has no acces to his old account and his books.
We find it very frustrating and started to buy paper books again.
