Be Careful Activating Codes from Third-Party sites.,
Verified Purchase(What's this?)
This review is from: The Sims 3 Into the Future [Online Game Code] (Software Download)
When you try to activate this code on Origin it will tell you to remove and re-install the base game. DON'T DO IT! You will lose all your bought custom content and it will be a major bear to get it all back...if you ever do. Instead hit the I button on this expansion in your My Games tab and install it from there. Read the Sim 3 technical forum for the stickied thread on this.
Other than that, no problems getting the code accepted and the expansion installed.
