re-activation doriсo

Hello. On the eve I bought, installed and activated Doriko. Today I reinstalled the operating system of my MAC and could not activate Doriko with my activation code. What should I do now?
P.S.: I probably found a solution in Steinberg :bulb:

It was perhaps not the best plan to install and activate Dorico the day before you planned to completely reinstall your operating system. The information you need about how to reactivate your license can be found here.
