same issue. Is dissapointing do an effort to get a legal Pc game (at least downloaded from the EA client) and find that the code is invalid OR USED FOR OTHER PEOPLE... maybe the next time I will going to download a pirated copy and get a keygen or some stuff like that... LOL
HOW TO FIX THE SERIAL ISSUE:
Enter your origin mail, (the one with the sims 3 game registered) etc.
1: Do the new sims3 account registration steps, and Erase the Serial auto typed. and continue without a Serial. if the account was created sucessfully, the keys should be there. (obviously for new users)
2: redeem your free points on the Account Details section.
3: be happy.
I did as furrydumb suggested. I left the serial code area blank. I then went to My Page (which I could now access,) and, lo and behold, the Sims 3 I had just bought was listed as a registered game.
Unfortunately, my attempts to get stuff through the Exchange throws up an error message saying I have to register a Sims game, so apparently the memo that I'm registered hasn't reached The Exchange yet. It's the weekend... I'll see if things clear up as the work-week starts up.
I used the EA Live Chat help. Had to wait over an hour to talk to customer service, who fixed the issue in under 5 minutes. World Adventures showed up in my game list, the 1000 bonus points were added to my account, and I was able to download the bonus content as well. I highly suggest that you get in touch with customer service. Just be prepared to wait. Have your origin account email and your serial number ready. Good luck!
I'm having the same problem trackrick is having. I understand that since I bought the Sims 3 via Origin, my game is automatically registered with the Sims 3 website but I'm unable to get anything through the Exchange, which is why I paid for the game in the first place!
