I'd like to transfer my license from my old PC to my new one. However (due to yahoo mail weirdness) my original download link is gone. So, I try to email support but every time I do so through the esoteric support page I get a mail delivery system email saying that my message could not be delivered.
This is the message I am trying to send.

Hello. I have a Spine Essential license on my old computer. I would like to migrate my license to my new computer but I don't have the email with the download link. The email my license is tied to is my email here I would like a new download link so I can migrate my license and upgrade to Professional in the future. Thank you.

This is the email I get when I try to contact support.
