You are almost certainly going to need to provide more details: what exactly
did you do, what was the "complaint" that xleap gave? etc.
I think it will be almost impossible to load the original pdb file -- you will
have to edit it so that the atom names match those of your non-standard
residue, and there is an exact one-to-one relation between the library files
and the pdb you load.
