Macbook stolen, can't access Dorico

I bought Dorico 3,5 elements 3 years ago, but soon after my macbook got stolen. I forgot about my Dorico, but now I have found time again to work with my music and would like to use Dorico as well as my cubase (which is new). I have the Dorico box with the License Redemption Card, but not my Download Access Code. On top of that I’m not sure which email I used when I downloaded the programme 3 years ago…
Any advice?

Welcome to the forum, Mic. I’m really sorry to hear that your computer was stolen.

You did at least register your Dorico Elements 3.5 license using the same email address you’re using here on the forum, so hopefully you should be able to reactivate your license on your new machine using this process:
