go to your my studio page and there you delete it
once you register a game in origin they auto reg it for you on your the sims 3 account but some games just do take awhile to show up on the my page but if you are having issue swith the code you could contact CS
They can be found here: https://help.ea.com/contact-us
Choose a category, a game and a platform for the contact options to show up.
If live chat is gray, change your country to US and make sure you're on US Business hours. It might also gray because they're very busy. Try later.
See this post if you have trouble with the site: http://sims3.crinrict.com/en/2012/10/how-to-contact-ea.html
What if my upload that I want to remove is showing up in the exchange, but not on my page? I had deleted it from the Origin browser where you enter the game. And so is no longer showing up on my page (didn't know it would do that.) But trying to load an updated version, that has a different name and the whole 9 yards, but it is telling me that it is already uploaded, but it is not, the old version is.
