Cubik Studio

Hey,
I bought "Cubik Studio" today (Friday 16.12.2016).
I have not seen that there is a possibility to register. So I bought the key through PayPal before I registered. What can I do?
I only got the E-mail from PaymentWall-Support.
Pls help me.

Sorry for my bad english im from Germany...
