Catch 22

I have the free license.  I cannot send or receive email because I lost my license key.
You have sent me my license key via email, but I can’t receive email because my account is not activated.

How can I receive my license key some other way than email?

Enter into your account via web browser and search for your license

I did finally find my license number in a backup, so I’m fine now.
Thanks for the suggestion!
