Forgot Acount

I bought Sins Trinity about a while ago. When I had the option, I activated it on another account. I had several other accounts on other websites, so I just forgot it over time. This hasn't been a problem much. I remembered the email address that I used for it origianlly, so when I had to reinstall it I just put in the right info. The most recent update has caused a problem. It makes me put in the email and password of the original account, I'm luckiy if I remeber the password. So now I figure, time to find some way to get a new code, so how do I?
