Calibre,Kindle and .mobi files
I am a long time Kindle user and I've been using Calibre for a few months now. I've run into a situation where Calibre says it can't install some books in .mobi format to my Kindle and it can't convert them to a usable format.
At the same time, I can mount my Kindle as a drive and copy those .mobi files to it and they work fine.
This problem has only recently appeared after updating my Calibre to the latest version.
What am I missing? Is there a plugin issue?
My Kindle 3 is running 3.4, my Mac is 10.8.2 and Calibre is 1.7.11.
