"Urbz" Sims 2?

[Bara no Uta]

So, I was at a 2nd-hand store and saw something that was for the Sims 2 computer games. I looked at it, it had the same front cover as the original Sims 2 does (and says "The Sims 2") but on the back it says "The Urbz: Sims in the City". Also the pictures and descriptions make it sound as if it is an expansion pack that lets you play in the city (not like the one in nightlife, but like it mentions sushi bars, tattoo parlors, and salons). It also mentions jobs, for example photographer.
So I bought it (it has 4 disks by the way) and was going to install it, figuring it was a spin-off thing. But every time I insert a disk, it tells me I need to put in the original disk (Double Deluxe)? O.o;


So my questions are...
-Is this actually the original sims with untrue information on the back?
-Could the thing on the back actually be an ad for a different game, and this is the original TS2?
-What should I do now? Try it on the DVD player??

I think that maybe the case was turned over possibly? And it was advertising on the back? I have no idea.
Maybe ifyou can, you should just uninstall and return.

I would suggest just to return the game, and buy another game. 3nodding
