So I just bought The Sims 3 World Bundles today at target and when I went to go to install them into my game it said the installation code was already in use, I just got it today and I don't know what to do!
Where did you try to redeem them ? On Origin or thesims3.com ?
See if this guide helps you: http://answers.ea.com/t5/The-Sims-3-Store/Guide-Sims-3-Store-Worlds/m-p/1589911
I don't work or have any association with EA. I give advice to the best of my knowledge and cannot be held responsible for any damage done to your computer/game.
Please only contact me via PM when asked to do so.
