I had been using 8.89 for a while, even after the 9.x upgrade came out. But all of a sudden, starting today, I cannot send e-mail. I have The Bat configured to use my gmail accounts, and had no problems prior to today.
The error it says on the status bar is:
TLS handshake failure. Invalid server certificate (The certificate cannon be used for this purpose).
The log says:

Under the S/MIME and TLS Certificates option, it's set to use Internal Implementation,
and whatever defaults pop up there. I've never altered or configured any of that.
For my STMP settings to Send Mail, it's set to
the Connection is Secure to dedicated port (TLS)
on Port 465
Authentication is set to Perform SMTP Authentication (RFC 2554)
and to use the same user/password as for Mail Retrieval
I went ahead and upgraded to 9.1.6 hoping that would fix it, hoping maybe some old setting was outdated, but the problem is exactly the same.
When upgrading, I used Windows RegEdit to export the prior The Bat settings so I wouldn't have to redo all my settings for my accounts, and the editor, etc. I say that just in case I pulled over something funky from the old version that's outdated (again, showing how little I know about the Registry).
I'm at a complete loss on what to do. Certificates and encryption are well beyond me. I appreciate any and all advice, and thank you for your time!
