That was the problem. I didn't have the latest version, even though it is what I just redownloaded via the Mac App Store. So, I have now downloaded it directly from Amazon and it gave me version 1.4. Oddly, when I went to install it, I got a message saying it was an older version than the one I already had installed, even though my installed version was 1.2 something. BTW, the default location for my files is [user]/Library/Application Support/Kindle/My Kindle Content. I'm not sure why this wasn't shown when I searched. DiapDealer, I am searching via Finder, selecting my harddrive to be searched. Perhaps I don't understand something about how the search feature works.
