Activation code for Dorico 3.5

So I very recently downloaded the new version of Dorico, Dorico 3.5. When I proceed to start up the program, I get a message prompting me to enter an activation code. When I enter the activation code that I got in my receipt, it does not work. It seems like I need a new activation code. How do I get this?

Restart the operating system. Call up the elicenser and enter the code in the menu. It worked like this for me (Mac).
