I don't mean to be rude or obnoxious, but you missed my post.
He's already used the code atleast once.
He can't give it away because it's at risk of having the code written down.
It would be key-sharing.
I'm pretty sure that if he gave it away to any of you, it could be de-activated.
If he bought a new version and sent it directly to you, with it never going to his e-mail, fine, but hes's had access to the code.
