Won't let me purchase napoleons – European War 5: Empire Review

First of all overall it's an ok game its definitely not the best European war game but it's still ok but I have been playing for a little while and I feel like spending some real money in the game but whenever o got to click on napoleon to try to purchase him but nothing comes up I mean if you don't want my money that's fine but i really want napolean so please fix the problem and let me buy him
