i cant put this mod in using the san andreas mod installer. i downloading it and have only been able to put in one mod. the 64 impala. every other mod i try and put in it says that its not compatible and i need a dff or txd file and some other stuff. i'm real new to the whole mod thing, so i have no idea whats going on. am i missing a file? how else would i put the mods in? is there another automatic mod installer program?
