How to get the full access for sims 3 community ?

Have you registered your game in thesims3.com????

Sorry,I can't realize what do you mean.

I could log into my account on thesims3.com.

I got 500  sims points which the system gifted me.

So does it means that I have registered the game on thesims3.com?

First of all, you need to log in to your account. Then go to "My Page". And at the bottom-left you can find "Register a Game" button. Click it and then you can register with the serial code (usually 20-digit serial code).

Please refer to this: http://answers.ea.com/t5/The-Sims-3/IMPORTANT-How-do-I-redeem-my-Humble-Origin-Bundle-code-for-the/m-p/1390706

There's an explanation how you need to register at thesims3.com.

I have typed in the serial number which I found in Origin(20 digit key).

But I have been told that the sn is invalided.

How to fix?

Is that means that if my game had been installed and my account had been created,it must had been registered?

since you got your points and everything, it seems to me that everything is fine. 

Was it just that message ? Can you post on the boards and download from the Exchange and Store ?

Thx for your reply

Is the board,exchange and store from the community in the game or just in the answer HQ? 

I have downloaded nothing in the store and post nothing in the board either so I'm not sure that I can do it or not.

I can log in with my user name,and the icon of the game and dlc is high light,and I can choose two maps in the game.

I'm a new sims 3 player from asia,so My english is poor,thx for your patient!

That would be on thesims3.com.

try logging in there and choosing the exchange and see if you can download something. It has nothing to do with the answerHQ.

You can checkout your mypage to see if the games show highlighted there (the ones you have)

I have 500 points in my account (Taiwan),and I have download a cloth mod and installed successfully.
