User blog:NguyenAnhLam/Lots weird things in my AoE3 game

Guys, I'm serious, I need your help. As I said, I prefer AoE3 to AoE2 because of the melee animations of the ranged units but I found 2 strange thing with my game although other players don't run into this trouble: The ranged cavalry units never do melee attack if the enemy units come close, some people told me to use Melee Mode but I don't know how to turn this on (take a look at my comment) because my game doesn't have any mode (the box is completely empty). Also, the ranged infantry in my game can use melee attack without using the aforementioned mode Second, the Militia in the Campaign (ex: Nathaniel Black), take a look at this picture. In my game, there is no Militia skin, they use the Veteran Musketeer one instead Last thing: My game will be come slow if there is a war between boats/ships (especially the cannon) and the cutscene opening the campaign Valley Forge makes the game become really slow (the introduce tooks almost 15 minutes) Can you help me solve those problems? I'm sure my game isn't trial as this is a birthday gift from my granny (she bought me a CD to install the game)
