I'm running Bookfab 1.2.0.4 and latest version of Kindle for PC 2.7.1 (update file 2.7.70978) Been very difficult to download.I have been able to get about 8 or 9 books downloaded after being forced to retry after numerous fails. Now, I'm down to 3 books that will absolutely won't convert. I've closed kindle and bookfab, reopened kindle, redownloaded, opened up BookFab as administrator, and nothing. I've attached log files. Hope it helps the developers.
