Error in convalidation

Hi, I recently brought Flip Boom Cartoon.

I had coping and pasting the product key.

And I done it.

The product says: “Congratulations you activated the product bla bla…”
After this, flip boom didn’t start, but I returned to the activation window which

says to write the activation code.

I Re-writed the code and in the next window, after this, a new window says “Congratulations”(again) “Press start to launch flip boom” i pushed the button but I returned… again, to the activation window.

Some help?

Sorry for my bad english whatewer.
