Re: The Sims 3 Serial Code

It's not a digital copy, though. I have the CD, just not the serial code. 
I lost the case with the codes in it, and all I have left is the Sims 3 Generations CD ROM. It works both for windows and Mac, and I wanted to install it in my MacbookPro. I already have the Sims 3 base game, late night and showtime installed. But without the code, I can't download generations.
All I need to know is how to get that.
