Hi, I'm having a problem with all my epubs in calibre (I'm talking about purchased ones, all of epubs basically). PDF, even pdf versions of those epubs, always work just fine.
Everytime I try to open one with ebook-viewer, there's a blue question mark either covering the whole page, or a small one on the upper left corner. If I open the pdf version, which I always create, it work. The weird thing is, thinking it very unlikely that they all were corrupted at the same time, I downloaded Adobe digital edition, which reads all of them correctly. That's a big relief, but I do not want to use ADG: i like Calibre much more.
The version is the latest (3.42 at the moment) and I own a mac version with my macbook air, updated as well. I have been noticing the issue in the past, but I realized just now that this affects all ebooks with this format.
Can you help me figure out what is wrong? I'm a very basic user, I use a lot the basic features, but I'm not experienced with codes and programming. I can follow instructions, however
Thanks in advance for any help!
