Julius,

While I am not certain what the error means, there is a button displayed right above the atom list which says "ADD A SITE."  I would suggest that having a unit cell as large as you do, along with rather weak scatterers such as N, C, O, and I assume H, it is probably unnecessary to have sites beyond the 3rd shell or so since these contribute negligibly to the EXAFS.
