I did not receive my free self‑hosted activation key

Hello, I installed n8n on Windows using npm install -g n8n. When I start n8n, I see this error: [license SDK] license activation failed: request/body/reservationId must match format "uuid" 400 Activation key is in the wrong format I followed the steps to request a free community license key, but I never received the email (nothing in spam either). Can you help me get my free activation key manually? Thank you

I’m currently trying to set up the Open Source version of n8n on my own server,
but I’m stuck because I never receive the email containing my community edition
license key.

What I’ve tried so far:

• Submitted the license key request multiple times
• Tested with several different email addresses (both personal and business)
• Checked spam, junk, and promotions folders thoroughly
• Cleared browser cache and retried the process
• Waited more than 24 hours for email delivery

Current situation:

• The UI shows no error message when I request the license key
• “Your license key is being generated” message appears, but no email ever arrives
• The n8n instance is running without the license key, but I’d like to unlock
  the additional features

Has anyone experienced this before or knows what might be causing the email
delivery issue? Any help, advice, or insight would be greatly appreciated.

Thank you in advance for your support!
