Hello, I have been trying for days to import my old Profile into my new Thunderbird file but it just does not work. I saved my profile duoexdi.default but now I can't replace it with the new one that was created. I go to tools, import, mail and it asks me the type of file, (Becky Internet Mail, Outlook, or Outlook Express. I don't have anything like this. It would make my day if someone can help me get my old profile back. I have exhausted all avenues. I have so many folders in my old profile that I would hate to lose them. Any help would be appreciated. Thank you. Jean P.S. I have done this before with no problem but I was using Vista or XP.
