E-Adapt_Document_Type_Unknown for EPUB Files with DE4.5

Report · Jul 01, 2017

Hello,

I have the following problem and hopefully one of u can help me with that:

I downlaoded Ebooks I bouth from the Google Playstore. I try to open them in Digital Editions 4.5 to transfer them to my tolino, but the above stated error appeared. I can open the files on my phone though.

What I tried:

- I re-authorized my Computer, that did not work

- I re downloaded the files, did not work

- I reinstalled DE, that did not work

- I tried using DE 3.0, that did not work

- I downlaod one of the books as PDF file and transferd that to DE and then to my Tolino, that worked.

So it does not seem a problem with the authorization of my Computer. However, I want the EPUB files and some of the bought books are not available as PDF, so it still does not work. Is there anything I can do?

Thanks for your help in advance

Daniel
