I just updated my Calibre and told it to add the icons to desktop and quick launch as I am a huge fan of calibre I have always updated but never ran across this before. I know it's something simple but brain is not firing very well today. I updated then went to open Calibre and my library is missing...where did it go, its as if I downloaded it for the first time, nothing at all in library. Any ideas? Thanks and I apologize beforehand for my inability to think today
