Updating Cubase AI7 to AI12 for free

I’ve owned a license for Cubase AI 7 since 2015. I’m now trying to upgrade for free to AI 12 but can’t seem to be able. Supposedly I should have received an email with the activatin code but I never got it.

Ive tried using the Steinberg Activation Manager but my license doesn’t show up in the grace period screen.

How can I update?
