I thought GOG was legitimate. I tried playing on GameRanger but it doesn't work. No one can connect to my hosted games and i cant connect to anyone's.
the game has an invalid key.
and when i try to update the game via patches, the app can't recognize the game and find out what version it is.

I would love to play online multiplayer. How can we do that ?

After what i have read, you need to use Gameranger..

And you can use whatever cd key you want to use ? but where to write it in ?

Unfortunately, the GOG-distributed version seems to mangle things badly enough that the official Sierra patches don't recognize the files.

THESE POINTS ABOVE NEED AN ANSWER. I do not recall buying, "Empire Earth: Gold Edition, But Without Multiplayer Support" when I made my purchase.
