I added in book in the last version of Calibre 4.0 this morning and afterward installed Calibre 4.1. Now I am unable to use Calibre. When I try to add a book, the program locks up in the Adding Books window when Reading metadata and adding to library (one book) reaches 100%. I have to open Task Manager to kill it. Also, simply clicking on Preferences locks up Calibre. I have never had a problem with any other version of Calibre and am using Windows 10x64 with 16gb of RAM.

Is there a way to revert back to Calibre 4.0?
