I have a large gap in my emails from April this year, and despite making numerous changes to settings I cannot get them to upload to thunderbird, so I can have a historical record. I have made changes to IMAP in both Gmail and Thunderbird, no joy, so went back to POP3 in both, again no joy, if I click get messages I jest get a "connected to pop.gmail.com" then it clears and nothing has uploaded. Any ideas it is p***ing me off.
