The Sims 2 HELP PLEASE!!!?

okay... about the codes. If you have all the cases, you should be fine. The covers of the cases and the names on the CDs should match up.... Okay, so in my sims2 games, all the codes are on the back of the CD case.... its a number code w/ a bunch of dashes. For my university, for example, it says 6MBK-GGCU-GCUR-DXSA-SPP6 you should have something like that. Look on the bottom of the back, in the white box. To download custom content, I get mine from thesims2.com click exchange and you could get anything. just click downlaod, and everything will go into your game itself.
