Describe the problem/error/question: I’m unable to activate my n8n license with the license key I received the email I received from n8n.

What is the error message (if any)? I got a message saying: Activation failed; the license key has already been used.

Hi @MyllenaCerq

Have you used this license before on a separate instance? Can you try generating under a different email for example?
