My husband has a Sony eReader and he purchased books from Kobo, downloaded with no problem. I purchased a few books from CBD.com which uses ADE to download and now his books are protected and we are unable to open. When he tried re-installing the books again he got an error message that they are registered to a different user. He attempted to download the books from his KOBO account again and gets the same message.
We've called Sony and they say it's not their problem since the books weren't purchased through them. We contacted Kobo and they're saying they need to issue a new license but it's been a week and nothing's been done on the ticket.
Does anyone have any ideas why this happened and how we can prevent it in the future besides only purchasing books from the same place?
