I bought a book from an online book store which said I had to download it through Adobe Digital Editions. Great! I did that. Paid money for my book. But then I tried to transfer it from the ADE to my eReader and it says I have no permission to copy the book!!! I PAID for the book!!!! I want to READ the book!!!! How do I override this so that I can actually get my money's worth out of the book???
