My key is not recognized as valid one

Dear Rotorsim, I have just purchased the Plus version, but I cannot activate it. The system insist that my key is not valid one. I have checked and typed the key several times, but without any luck. As you can see in attached picture, my key is the one you have assigned to me. What should I do? Best Regards Vita Zenisek
