The Sims 3 World Bundle code has already been used
I bought the Sims 3 World Bundle which includes both Monte Vista and Hidden Springs. After installing Monte vista, the Game Launcher opened and prompted me to sign in to redeem my code for Monte Vista. I tried inputting the code in the game launcher's window as requested, and when that didn't work I tried logging into my online account on thesims3.com. Both times, when I input the code, I received an error message stating the code has already been used, but it can't be since I just received the game in the mail today. It's brand new. How can the code have already been used? How do I get around this error?
Hm, maybe the code has already been redeemed but the launcher isn't indicating it properly? Try launching one of your saved games and open the main menu through there. Sometimes the worlds show up in the Downloads Dashboard there instead of the actual launcher.
