I am SO sorry for the belated response, I didn't see a notification of another reply.
Thank you so much for doing these conversions, and maybe you gave me a boost by the file name with v 1.3.6 A
. I will be trying this out again with that version, and keeping my fingers crossed.
And thank you for the FeedBooks link. I had downloaded books from there quite some time ago, and they all seemed to be in plain-text, a la Gutenberg. Who knew they have nicely formatted books... (would be nice if they gave a hint how the book looks)
Thank you for the time and trouble, Santa better be generous with you for your good deeds.
