Why cant you use the serial code twice

[accesorise123]

my daughter deleted the sims 3 and i am trying to get it back but when i type in the serial code it says it has been used what am i supposed to do

A serial code can only be used once - for one account only. Therefore, you'd have to be using her account or the account that you originally redeemed it on. It's just the way things work.

If you need assistance with recovering the account, please contact a game advisor:  http://eahelp.ea.com/en/ . For help with navigating the site, see this: http://answers.ea.com/t5/Beta-Archive/How-to-contact-a-Game-Advisor-using-the-new-EA-Help-page/m-p/2...

I have the same problem. But I can't log in to my original account cause it got deleted.

@AphmauAndEin  You can try contacting EA customer support to see if there's any way to recover your old account, or to merge it with your current one.  But other than that, you unfortunately might be out of luck.
