Serial in Use error msg

Can’t activate Circle2 in a new machine. Get the error msg “serial in use” but there is no link to reset it in my account page. Also, it shows that no machine is registered.

thanks in advance for your help


@christian.eduardo, can you send a message to and @Julia will have a look.


Just sent the email, thank you!

JusT got the same issue, trying to install Circle on my new PC (2 slots available) but same message “serial in use”
Email sent


@Julia can you please look into this? I sent an email yesterday but still nothing, I really need to activate Circle to print some stems, thanks!!!

Hi Andrea @Residente I’m on it!
