Need to Re Register for Avast 5.0 Need Help

Hello Again,
I recently placed Avast 5.0 in one of my computers [Free Edition] and when i was registering i made a typo on my email address. I was wondering where can i Re Register to get a code to continue my Avast Free Subscription for 1+ year(s). Cause there is no option in Avast.

Thanks in Advanced, Anar.
