Problems with axe throwers and custom maps!!!!

[Elestraw]

I am new to this mod so forgive me for the noobiness and stupidity (I am also a steam user not CD)

1.ISSUE

The dwarves axe throwers crash the game. Every time i use them it crashes and comes up with (unexpected error). The only thing i know about this is it is something to do with the (data/model_missiles) folder but here is the thing, when i first downloaded the mod and all is patches the different downloads came in different folder so i placed all the downloaded folders in one of the downloaded folders which was called (Third_Age_3). The last one i saw that was left out was called (data) and i looked inside it and it had another folder called (model_missiles). I tried to put the in the (third_age) like all the others but it already had a folder called (data) and it keeps asking me do i want to replace it and i say no. So i thought i would have the stupid idea of changing the name from (data) to (datar) an that still doenst work because of the axe throwers keep crashing.

WHAT SHOULD I DO!!!!!!!!!!

2.ISSUE

None of the costume maps such as Helms Deep, Black gate or any of the cool ones work. I haven't played the campaign i just wanted to go straight in on the custom maps and recreate the battle of helms Deep or minis tirith but every time i lunch it i puts me in a random open green map? I looked at the section and it has a box cross going though its and say (user dined custom...), something like that

PLZZZ I KNOW ITS A LOT BUT IM GETTING SICK OF LOOKING FOR ANSWERS ON GOOGLE OR THE FORUMS. IM A NOOB I JUST NEED HELP!!!!!!

Hello!

That models_missile folder goes into your steam/.../M2TW/ data folder, Merge Folders when asked, Copy and Replace Files if asked.

Also, custom battles have to have the correct Culture set, and level of the settlement set. If it says: Black Gate ( Huge Town, Custom culture required) then on your left set these two as it stands in the "brackets" of the custom map you want to play with.
