SMTP error

I recently bought a  laptop with Windows 10. I use Gmail and since Windows 10, I get an SMTP error from my Gmail accoung through eMclient. Also, when I send an Email it sends 2 (dups).

Hello, not quite sure what you’re referring to, what version of eM Client are you currently using on your computer, can you please check the exact release number in Help > About? What kind of error are you seeing, can you please make a screenshot of the error or navigate to the Log tab in Operations when it occurs, copy the content of the log and submit it to us here on the forum?

Thank you,
