need product key activation for brucefgrant@gmail.com

I bought a licence but cannot find the product key. Please could you let me know why it has expired on email brucefgrant@gmail.com. thank you, Bruce

Hi Bruce,
I see that you registered a free license and it is active on our servers.
If you have problem with a different license but don’t want to post the address publicly, contact me at rust@emclient.com and I can send you a reset email with your activation key and licensing server credentials.

Regards,
Olivia
