It may seem silly, but i just bought the retail version of this game today. I open it up, everything looks ok, i put the game in, download it, and no problems. Until i have to update, which i would have to do since i have a Windows Vista 64 bit, and the latest update is my only chance of playing the game without my computer blowing up.

It ask's for a Serial Key, and for nearly an hour i am looking at every page of the training manuel, and looking at every single angle of the box. I don't know if i just got a botched retail version with no serial or they have it conveniently placed in the most inconvenient of places, if there is such a place, let me know, if there isn't, and i just didn't get the serial key, please let me know so i can complain, get the other retail version at Walmart, and take that serial key.
