I upgraded from free to Pro 4/6/2015. Recently I purchased one for an older friend of mine who needs assistance and loves your program on Aug 22, 2017. I still have the order id. I tried used his name however, I did use my email address. It looks like all I did we re-purchase the my existing license ID. If thats too bad on my part so be it. But your purchasing system makes it really hard to purchase a license for another user.
thanks
