INTO THE FUTURE KEY REGISTRATION ISSUE

Hey

With serial codes stating they're invalid, you most likely will have to contact EA, they can be found here: http://eahelp.ea.com/en/ . For help with navigating your way around, see this: http://answers.ea.com/t5/Beta-Archive/How-to-contact-a-Game-Advisor-using-the-new-EA-Help-page/m-p/2161281

With registering codes on ORIGIN and not being able to find your code, etc please see here: http://sims3.crinrict.com/en/2013/09/how-to-find-your-serial-number.html

Please keep in mind that if you bought the game off Origin, it is AUTOMATICALLY registered FOR YOU! To get your accounts connected, simply use the same details as you use for Origin.

If you have bought the game second-hand - you will not be able to re-register it. Games can only be registered ONCE.
