Help downloading

I downloaded the mod, and when it finished the first download thing it came up on my documents folder, I clicked Extract all files and then it started. It has finished now and I cant find how to play it, when I click the Mount&blade icon on the desktop and look at the box that says current module (or something like that) it only says native. Also Im not sure if this is good or not but I found the  MB_1257_Edition_v14b[1] folder in "My Documents".
Is all that ok? Its my first mod download so I confused -.-

Ok, nevermind I found a friend to help me.

i too got a problem with the mod, when i've installed it and hit play, it loads to 25% and the crashes and a i get a pop up that says "cant find costume" or something like that, please help me someone
