Nobody else is posting about this problem, so I suspect I have a setting not right. I download books from Amazon and the plugin removes the DRM. However, I cannot open the book in Calibre. It says that the format is not recognized. If I use the ebook converter (
http://ebook.online-convert.com), it converts to mobi just fine and opens fine in Calibre. This problem started when the azw3 format began, but now even some azw formats are doing this.
I have the latest version of Calibre installed and still have the problem. Am I missing a plugin? Is there a setting wrong?
