I have forgotten my old account with my old Sims 3 Games on! Please Help someone!

I have recently bought new Sims 3 Expansion Packs and I wanted to redeem free stuff from The Sims 3 Community Website. I then realized that I didn't know what my account email or password was because I now have a different email. I tried my old email and some passwords I might have used for the account. I really wanted to get my account back because it had all my other Sims 3 Expansion and Stuff packs registered on there, I tried going on the 'forgot password' link but that asked for an email which I didn't have. I remember my old accounts user name, Leonthelion2 or 3 I think but anyway I was forced to make a new account with my newest email. I then registered my two new Sims 3 expansion packs on there. The questions I am asking is how can I get my old account back so I can then redeem all of my registration gifts. Please help someone!
