I reinstalled the game a while ago without reregiersting. I tried to update my serial number so I could use v 3.1 but I have a problem. I changed Email adderess a few months ago so it's not the same account email that I used regesterd with.
It keeps on saying that it's not the right serial number with the right E-mail address. I can't figure out what to do. I tried using the same email address I used before this.
