What mod are you trying to install and for what game, you have to give us more information to help you out. Since I mod mount and blade I reconize the CommonRes\costumes_a.brf but first glance are you trying to get a mod to work on warband because I think that's your problem.

yes! thats for me 2 and yes its for warband how do i fix it!

I don't really know as I only know that this problem appears when trying to get a m&b mod to work on warband. There is no way to fix as your trying it on the wrong game. If the mod is for warband then I don't know how to help.
