I downloaded an E-book, didn't authorize my computer then. Read the book fine. Later I created an ID. Now, I try to open the book and it says I have to authorize my device and when I do, it says the book has already been authorized by another vendor ID. How do I get it working?
No. If you open a ebook without a id you get read the ebook only untill authorize the programm. Ask the resller of the ebook if can get a new file. And in the furtur check if has authorize ADE before open a ebook.
