I'm having a serious problem with Thunderbird.

Recently I started the program, but it did not load my profile. He opened asking to configure the e-mail as if it were the first time I was using the program.

I checked the folder. Thunderbird and the file "profile" the key "path" is set correctly for the profile file "exemplo.default".

Does anyone know how to fix it.

Otherwise, I'll lose all my important messages forever.
