mod loader help !!

i am trying to install the planes mod for 1.7.2 however when i try to run the mod loader i get a screen saying it cannot find certain files form minecraft .i have followed all the tutorial steps and when i tun minecraft the items mod works but not the planes.i have tried placing the plane mod in the same folder as the item mod and using a seperate file and it does not seem to make any difference.
i have toomany items mod and its works fine is this because i have two mods at the same time i thought mod loader helped to solve this.
