I am receiving the upper error messages when loading an ePub-File in "Digital Editions". For the reason, I work in a support team for eBooks, I could check that the ePub files are correct and can be downloaded and read on another test system (other Adobe ID). Can anyone of you tell me, what the error messages are trying to tell me? The format of the messages is typical Adobe, so I hope some support member can say anything.
Thank you for your support!
ADE is complaining that the epub file is corrupt - it has a bad ZIP structure (epubs are actually zip file of a very specific format). I would suggest recreating the file in question.
thank you for your answer!! I think that will help a lot.
