Several months ago I sought assistance for what I thought was a problem with Calibre updates causing all titles and info on the device to be wiped clean. As there didn't seem to be any type of solution I continued to use the software and did not experience further issues. Last night I added ten titles via Calibre to the Kindle Paperwhite. As it was late, I decided to wait until this morning to send them to the Kindle. When I opened Calibre the entire slate of information was gone, all titles that were there since February - gone; all the left side column info numbers - gone - reset to zero. I am guessing my original idea that the disappearance of info was somehow related to updates was not valid. My question becomes - can anyone out there offer an explanation for these mysterious happenings? I'm using the latest Calibre update (1.28.0) OS X Mountain Lion on a MacBrook Pro and Kindle Paperwhite (second release) I thank you in advance for any tech advice you can offer.
