HELP! Can't send mail -- "Folder has been deleted"

I use em Client as front-end to my gmail. Everything has been working great. All of sudden I tried to send email and now I get this error:

   Can’t process message
Couldn’t process the message because the following error occurred. Consider selecting a different account to send messages from.

       Folder has been deleted.

I have tried the following:

  1. A different gmail account
  2. Deleted my gmail account and remade it
  3. Logging out and back into em Client
  4. Rebooting my system and em Client doing a check on the database.

Nothing is working. Please help.
Thanks,

I have just removed em Client and reinstalled it and the problem still exists. Please help before I go looking for another email system.  Thanks.

Hi Brian,
Have you tried to reproduce this issue via webmail? Gmail accounts should work in eM Client.
Also you can send logs and screenshot of the error, to copy logs go to Menu>Tools>Operations>Log and copy with Ctrl+A, paste to notepad, then send the file to cooper@emclient.com.
