error opening epub in calibre viewer

[anagel]

I have this error when I try to open an epub in calibre. I have redownloaded the book from my source but that hasn't fixed the problem. Is there a plugin that would help?

Any help would be appreciated.




calibre, version 4.5.0

Epubs are just zip files with a different extension and some expected content. The last line says the book is not a valid ZIP file. That suggests the file you downloaded is corrupt. You could try and open it with a compressed file tool and seeing what error it gives. Other than that, you could try to download the book with a different browser, just in case something strange is happening. And report to the source of the file that there is a problem with the file.

Thank for your quick reply and thoughts. Yes I totally thought it could be a corrupt download. I deleted it from the calibre library folder completely. and then downloaded it again and same error. I have sent a message to the source of the file and hopefully they will figure it out. Thanks again!
