After accidentally closing Thunderbird, two message I was working on were still open. I went to Windows Start and clicked on Thunderbird and it opened but neither of my two email accounts were shown. I was able to get to Support by clicking on Help in one of the messages. I tried "Set Up Your Existing Email Address" and received the message "Configuration found in Mozilla ISP database." When I clicked on "Done", the message "Incoming server already exists." Available configurations IMAP Keep your folders and emails synced on your server Incoming IMAP I SSL/TLS imap.gmail.com Outgoing SMTP I SSL/TLS smtp.gmail.com @ Username waynestiefvater@gmail.com When I click on "Account Setting", a screen appears that shows the accounts for both of my email addresses, and the settings appear to be as I remember them. Everything seems to be fine but Thunderbird simply won't load with my two email accounts. A week or so ago I had to delete all of the Cookies on my computer to get another program to work. I don't know if the Cookies possibly needed for Thunderbird to load were deleted and that might be the problem. It shouldn't be the cause of the problems I'm having now, but the Profile for Thunderbird is at the root of the C: directory: C:\0-FFox\Profiles. That was done to shorten the length of the file addresses. Many thanks! I really appreciate your help! I use email a lot every day and I hope the fix will be simple!
