In order to diagnose a problem with the DeDRM plugin I have tried, multiple times, to reboot in debug mode, both from the menu and by using Shift+Ctl+R. Each time, the program hangs. Nothing is clickable and when I minimize the window I see the box that reads "Starting up, please wait...Initializing user interface".

I end up having to kill the process.

Anyone else experiencing this? Any ideas?

UPDATE:
After killing the process, I do get this log, which doesn't seem to me to shed any light:

Thank you.

Your debug should look a lot like this:

You seem to be having a problem with your database or HD.

I recommend you rename your library folder then start calibre--it will start with a new empty library--then change to your old library and run library maintenance on it.

P.S. I have no problems with DeDRM
