I have a new Cubase Pro 12 Upgrade from AI.
I can download the Pro 12 , afther the download they gives an error.
You entered a Download Access Cod for a product upgrade but you do not own a license to which this upgrade can be applied.

Please help me
Thank you very much!

Where did you enter the code?

Please run the Steinberg Activation Manager to check which license you have, and compare that to the upgrade you purchased according to your receipt/purchase confirmation email.

If you purchased the wrong upgrade, please request a refund:
