It's alot to ask, does anyone have a share pack activation code for skate 3 please?

So i let my friend borrow my new skate 3 game which i had only played for like a week and didn't realise it had an activation code. After 5 months i got it back and found out that he had used my activation code. I would be realy happy if someone knows of a way to get one for free or if anyone can give me one. Thanks guys
