So i purchased the Rome total war gold edition last week and installed everything. have run into a few problems and i don't know what to do.

First it never asks me for a CD key. the manual mentions one , it even comes with a green card that has one on it but after installing and playing the game i am never asked for a CD key.

when i download the patches from the Sega west website i run them but before they install i get a issue of " Rome total war gold has not been installed on your computer"and then the program shuts down.

does anyone know the cause/fix of these two problems?
