Hello,
Calibre crashed when my windows session was locked.
I tried to launch calibre again... nothing happened.
As I was on an old portable version on USB, I updated it... nothing.
I updated the 64-bit version on the computer... nothing.
I went on all the steps of the FAQ "
Calibre is not starting on Windows" without success.
Here is the result of celibre-debug -g :

The above exception was the direct cause of the following exception:
