It's working correctly, and the .REG file is not obviously a method to surpass the 6 activations limits.
As clearly explained in the product manual, and in the FAQ in this website, when you exceed your maximum number of activations, which is 6 per order, you have to EMAIL SUPPORT, asking for a reactivation, not post on the forum as if your message was a bug of the program, because it's working correctly, it's just that you exceeded your 6 activations.
