App not starting after update to 9.0 and a random pc crash

Hi,

Now I get the error message "Thunderbird has ceased to run" when I start the app, with those details even if I reinstall the app over the folder:

Problem signature:

I suppose some file got corrupted, and I wonder if there is a way for me to import to a fresh new installation all my newsgroup account settings such as folders and subscriptions ?
