Thank you again, guys, for this fantastic app. Unfortunately for all of us, Amazon is constantly changing things.

When I use KindleUnpack 061 to split a .mobi file (produced by KindleGen 2.8) into Mobi7 and Mobi8 ebooks, the resulting Mobi7 .mobi file cannot be opened in the latest version of Kindle Previewer, 2.8. It gives an error message "cannot open the file book.null".

(The original .mobi was built using KindleGen 2.8 from a "web page, filtered" made in Microsoft Word 2010.)

That same Mobi7 file from KindleUnpack 061 opens just fine in the latest Kindle for PC and in MobiPocket Reader (and when I side-load it on my Kindle via USB).
