Thunderbird empty frame and error message(s)

jbclem

After working normally for more than a year, last week when I started Thunderbird there was a popup page with an error message that kept repeating itself "Sorry, we're unable to communicate with our sign-up server. Please check your connection." And behind this error page was the main Thunderbird frame with tool bars, but nothing else. All the email and email folders had disappeared.

I have the same Thunderbird setup on my upstairs desktop computer, just like this one, and it's working perfectly. And no connection problems anywhere, I also have other email programs that are working normally.

What does this problem look like? And is there a way I can check the profile to make sure the email and email folders are still intact. Is there a way to know if the profile is corrupted, and does Thunderbird keep duplicates of the profiles?

I'd appreciate any troubleshooting help...

This happens when TB loses track of the profile - it acts like a new install. The profile is still there, but the prefs.js file is probably corrupted:
