Hi folks When I tried to start up Thunderbird this evening, it has taken me to a set-up page. I seem to have lost all the settings, all my previous (about 3000 !) e-mails in my Inbox. I obviously don't really want to set it all up again, but it has been working for years without a problem, and then suddenly this happens. I had now a 'warning' message saying that Mozilla Thunderbird wants to make changes to your computer - do you accept? I don't want it to make any changes unless it is to revert back to how it was. Can anybody help me? Thanks.
