im trying to delete then replace the m60 dff,and txd from my vice city gta3.img and every time i try to "delete" the m60.dff i get this exact message "Error dir file error! it might be in use...now exiting..." the mod is an m49 that replaces the m60,and the mods fine....it worked before but i had to re-install the game because of the long night mod.....
