Shortly after a recent microsoft update, Thunderbird stopped working entirely. No downloads from gmail, manually or automatically, I can't send emails either and I get an endless message that it's trying to copy the outgoing email to the Sent folder (I think), but it never actually does it, and the message never goes out. I've gone through a bunch of the suggested fixes from various forums and checked the settings. The only one that was different from the recommended settings was hardware acceleration, which I turned off. I'm at a loss. It won't even download manually when I hit the button for "Get Messages." Any help would be greatly appreciated. Thanks
