I did all the above, except for the factory reset, but still could not read the book. So, I contacted Kobo and they suggested I download version 2.0 instead of 1.7.2. I did this and was able to get everything authorized. It indicated that both the computer and my Kobo device were authorized under the same Adobe ID, so I thought everything was good. I went back to our Public Library and borrowed a new book. It downloaded and transferred to the Kobo with no problem, but it STILL would not open on the Kobo - gave the Oops cannot open message saying that it was not authorized.
At this point I spoke at length on the phone with Kobo Help. He checked all the aurthorization settings on the device and on the computer everything seemed fine. We deleted the books (I had downloaded 3 and none will open - they are all e-pub books) from the device and then recopied them to the device. They still would not open on the device. We deleted them from the device again. Then deauthroized the computer and the device. Authorized them again and at this point the books when I attempted to drag them gave an error message and would not even copy over to the device and also would not let me return the books to the Library (error message again) At this point the Kobo rep felt I should contact you at Adobe as everything seemed to be OK from the Kobo standpoint. He felt that I should talk with you before I tried a reset.
Before writing this, I decided to try renting a different book from our Public Library, which I did. It came into Digital Editions and transferred to the Kobo Mini. I ejected the Kobo from the computer, unplugged it, and tried to open the book. Same Oops! message. So I have deleted it from the device. At this point I decided to return this book. In the process of doing the return, Digital Editions stopped working on me - asked to Debug or Close. I clicked on Debug. Next Screen the only option was to Close so I did and then restarted Digital Editions. At this point for some strange reason, the 3 books that I was working with previously, were now able to be returned with no problem; however the 4th book, the newly downloaded one, will not return and gives an error message when I try to do so.
I am stumped and really need help to figure this out. Why will the books not open on the Kobo when everything seems to indicate that both the computer and the Kobo are authroized properly with the same Adobe ID and the books copy over to the Kobo with no problem.
Any help anyone can give will be greatly appreciated.
