Ok guys, I have the Sims 3 base game, WA EP and high end loft stuff. I installed all 3 of them in this order.
First I install the base game. After done it, I didn't touch anything on it and then installing the WA with prompt to update. And I didn't also do anything on the expansion pack. Then I installed the stuff pack. I opened the game with no error, but after the loading and on my household screen, it popped out a message about "disc authorization failure".
How do I fix it? Please help. Thanks a lot.
