Textures dont save

[TattieBoJangle]

Hi guys i have been having trouble with the material editor it wont store my _N maps and _S maps when in the Material editor i click load on where the _N should be it loads in fine but when i save it vanishes.

EDIT

Also getting this (check failed as material pass does not contain any texture unit states!) and it causes some models to go white.
