Thanks, kryo.
However, I've run into an unanticipated "wall." The copy of the game which I bought from Amazon.com was "used." So, although I could load it and I can play it, the previous owner apparantly registered it, preventing me from registering it...and being able to download the 2.04 update.
As I previously bought GC II Gold, but never played it...because I saw the opportunity to buy the used copy of GC II Ultimate Edition, I really don't want to spend even more money...just to get another new Key from Stardock...in order to get the 2.04 update.
So...I'd just like to verify my understanding from your helpful reply that I won't be "missing" anything if I install a major mod to my 2.02 version...and that I can download and install, say, Altarn's Polished Twilight of the Arnor Ver 2 mod and that it will run perfectly fine without my first obtaining and installing the 2.04 update...am I understanding this correctly?
Please forgive my trepidation but I'm quite new to "game modding."
Thanks!
Mike
