I updated the game to 1.5 before I installed just as the instructions said, then installed EB(which took a really long time; is that normal?). Maybe I'm doing something wrong, but whenever I open the game, it's exactly like RTW vanilla, with the 3 Roman factions being the only ones available for play. The only difference I can see since I installed EB is that the little loading bar is green instead of the default color.
Thanks in advance to anyone with help.
