I installed it, but it's not loading (strange video!)

Ok, I installed the game, but when I go to run it, it loads up Black and White 2, not Civ IV! VERY DISAPPOINTING. In fact it even lets me PLAY B&W2! ????

Maybe I'll have to wait until I get the game TOMORROW!

I'm so desperate I bought B&W2 just to install something! Since CivIV isn't out today!
