I'm assuming you didn't link your old account to an ATA ID or to facebook.

If you did, go through the tutorial until you get to go to settings and are able to log back in.

If you didn't send an in-game request to support via help to ask them to get you back on your old account. Don't forget to tell them the exact spelling of your account name and answer all questions they give you as soon as you can. It may take a bit of time to get back to you, but they will, and it's important that you do answer their questions.

Good luck, and the next time, make sure to link your account to an ATA ID or facebook. (The most important thing is that you need to link your account so you can recover it on your own next time) -my post was too long, so I had to split it up.
