duplicate of later thread since it has a image /questions/1450665. You could have edited the thread to add the image.

On powering up my PC this morning, opened Thunderbird and everything was gone - email settings to my various accounts, settings, calendar, addresses etc nothing is left at all

All I have is a basic screen : "To set up your existing email address" etc
