Lost e mail address used to register

I use the free edition of eM Client My license expires in January 2013. I have got my license number but will need to use my current email address to renew the license (I think). I need to know if I will need the original email address I used - when I come to renew in January 2013.I have cancelled some of my email accounts and don’t know which one was used originally.Thanks.

When using Free version, your licences are renewed automatically.

When using Free version your licences are renewed automatically, but I have checked it in our licensing system and your license is registered with michael346harrison@btinternet.com address.
