I have been using Thunderbird for about a year. I had a problem with my internet connection a few days ago, which has been resolved. Now, I can only see email messages from 7-22-14 and prior. When I click on Get Mail, I see "Downloading message 1 of 45 to docfalck.com", but only a few messages (the same 2 or 3) keep downloading and then I see "No messages to download". Please help me retrieve my recent email messages - thank you!
