thunderbird fails to open
this happened after a reboot i forced because the address book failed to work (seemed empty) and thunderbird claimed it couldn't close down
next thing i know on reboot is dead 'bird
and all i get is a window with the info shown in the image below
the win10 install suggested errors on the c: drive (since fixed, but the problem remains)
what is going on and how can i fix it barring a fresh install and losing a lot of interim mail and all my filters i would be happy enough to simply retrieve the profile (and missing emails) and start from scratch
the only profile with a current date is called ja9848vt.default-release and is a mere 37mb with 706 files
is all the previous *.default completely lost?
