Who said I was pirating it? Like I said, my brother bought it. Now I have installed the game also from his copy. My brother visits me many times and we would like to play it online on this system also, without constantly bringing the CD's to my place...
I was wondering why we cannot use the same serial... and why it's INVALID...
