Cubik Studio

Although I own Cubik Pro I bought a new Cubik Studio account as a thank you :-)
But when I click the link in the "Purchase of Cubik Studio"-email and fill-out the register form of the activate product the register-button stays dead. I can't click it to register. Please advise.

Have you definitely filled in all the fields and also check the "I agree to the Terms of Use" checkbox?

I just tested the form now and it works fine.

When I now click the link I have another "Activate Product" form, this time in name of Nobita2, however when I enter the password and check the I agree box and click activate it freezes.

Tried again and got it working I think. Thanks!!
