So I just got around to installing my copy of the game. Except for this tiny problem. I can't seem to find the product activation key anywhere. Maybe I am just an idiot and not seeing it, but where is it printed in the manual? Because I can't seem to find it.

For my UK retail copy the key was on a sticker below the DVD itself.

I've got a north american copy. No stickers inside the case, nothing printed on the dvd cover, nothing on the dvd it self either.

It's the same in the NA copy. Sticker is inside the case below the DVD.

For my North American copy the number was on a white sticker below the DVD inside the case.

"Return as defective" time for you.

Thanks. I suspected as much. Wanted to make sure before I did return it. Thanks again for all the replies.
