I have used Sony for the past 5 or 6 years. They recently stopped selling books and migrated their customers to Kobo. In uploading the Kobo site it looks like I added a new Adobe ID. Then my reader and computers were out of sync. When I try to download books I get that they were already downloaded by another user, but also that they are in my library. However, I can't find them, and if I do download, it gives me an error message that the book is DRM protected. How do I get to the point where I can download books again?
