Attached is the debug log of the issue i'm experiencing. I purchased a Kindle book from Amazon (.azw file extension). When i attempted to add it to Calibre, the message "Reading Metadata and Adding to Library" was stuck on 0%.
I want to convert this file to .epub because although this book has an .azw extension, it's basically a pdf which is hard to read and i have to constantly zoom in to read anything. I also want no restrictions on copying text from the book. How can i resolve this? Thank you in advance.
