Hi, Today when I tried to open TB 78.6.1, there were no email accounts visible in the left hand pane. I have 7 email accounts running through this mail client and I can see that there's something working because I get the usual incoming email alert when I receive an email but cannot open it and it's not visible anywhere in the TB window. I did read of deleting a global-messages-db.sqlite file but have done this several times to no avail. I have also tried disabling my firewall, reset in safe mode and nothing happens when I select tools>options. Has anyone else had this problem? It was working yesterday, Screenshot attached. Thank you
