World Adventures Update Problem.

Okay well i got Sims 3 and i decided to download World Adventures. the problem is when i try and install it, it says.

" The Sims 3 needs to be updated before the product can be installed.
Setup will not attempt to update Sims 3. Do you wish to continue.
Yes/No.

If you click Yes it says
Update in progress. Please Wait...

30 seconds later it errors saying
"Update of Sims 3 failed. Setup is unable to continue.


I pasted the original launcher and the dll file and it still does the same thing.

The version of Sims 3 i am running is 1.0.632.00002.

How can i fix this problem?

//EDIT


Updating the Version now, but a new problem has popped up.
