I have bought some books, apparently generated with a program called "Papyrus Author". Most of them can opened with ADE, but some not.
The Books which can not open in ADE have a Title with a "&" in it like in "Cream&Butter".
The error message is (translated from german version):
Open butter&cream.epub not possible
In this media has been found errors
If I unzip the epub file and edit in the OEBPS\content.opf the line
The document opens, but with no cover.
To show the cover, I have to edit OEBPS\cover.html
<img src="images/cover.jpg" alt="Cream&Butter"/>
<img src="images/cover.jpg" alt="Cream_Butter"/>
BTW: I work on a PC in German with Windows 8.1 64bit. ADE is in Version 18.104.22.168333
