Oh my, you input pdb file has lots of problems. First, the waters at the
beginning should be removed: Amber has several built-in water molecules,
and you don't want to use antechamber to create a force field for water.

Second, for the LIG, take just *one* residue (of each chemical type) and
give it to antechamber; then load the library and frcmod files you get
into LEaP, finally using loadPdb to read in an edited version of your pdb
file. (Editing: make the water atoms and residues have proper names; put
a TER card between each individual molecule.)

...good luck....dac
