Well about a year ago I had given all my CS product details onto a forum, a form of pirating, and I still suffer from it today. Once a hacker has your email and order number, they can reach all other products that you have bought and can record your new order number. This seriously needs to be amended, so maybe one can have a password to change. I regret giving my details out, and all they need is 1 order number. And I know what is wrong with the 777. The hacker probably has his own CS account after his own purchase. On the account there is an option to find lost products. He has probably used it to take it for himself. This is my guess.
Sorry,
Pete
