So I've just re-installed Medieval II: Total War, and it's expansion pack, but for some reason I can't play as all the factions that I remember I could from years ago. I liked playing the Denmark with their axemen and shit, and I'm pretty sure there were some Arabic ones in there somewhere too, and Russia, but now all I can seem to choose between is England, France, Milan (seriously, I get Milan instead of Vikings?) Scotland, Spain, Venice and perhaps one other not entirely memorable one.

Am I missing a patch? Do I need to complete the campaign mode with one of the boring races first? I want the Danes and Holy Roman Empire damn it!

HELP.
