Well, I managed to solve my problem, but it was strange: when I installed GI, I chose english language (and not the "default", portuguese - maybe it is the default because my Windows version is portuguese. But I got scared and chose english, and couldn't play). I uninstalled and reinstalled GI, now accepting the default, and voilá, my serial got accepted! So, serials have languages ??
Nevertheless, I must say that I am impressed with the fact that the game menus are indeed in portuguese ! Amazing
Now back to AACW...
