older games on new computer

I am having some problems with 2 games that i purchased. They were originally installed on an older computer, and now that i have a new computer, i have them on it but unable to play online or register as the codes are already in use. So i can't play these on my new system. my old computer died and was unable to back it up, and as it had multiple m/b breakdowns the back ups done were no good.

The games in question are...balltefield bad company 2, and medal of honor.

Another problem i am having is updating my email address. the old one has been slighty changed and the account home page doesn't let u change it when u can't access the old email.

Any help with these would be great.
