The Smashwords file sideloaded worked fine. So, I guess this is a Calibre conversion issue.
The symptoms of my problem are even weirder. The epub-to-mobi files are read with no problem on my Kindle KB, but perform the "open then close" routine on my Fire. (But not *every* converted file, just some - and I haven't been able to find anything in common among the files that won't open.) I've tried resetting/reinstalling/reformatting/reconverting with every option I could search for on this forum, the Amazon Kindle forum and the Calibre help section.
At my wits end!!!!
I love my Kindles (Amazon WILL synch last page read on sideloaded files) and Calibre, but I've run out of things to try!
This probably should be moved to the Calibre forum - Mods, can you take care of that?
This is such an odd thing. Let's do a factory reset and then come back and see if that fixed it. Are you using Calibre with Windows or another O/S?
