You need to have additional commands on the Gaussian route card, generally:

#HF/6-31G* SCF=tight Test Pop=MK iop(6/33=2) iop(6/42=6) opt

The recommended way to get your Gaussian input is using antechanmber itself,
e.g.:

antechamber -i <name>.pdb -fi pdb -o <name>.com -fo gcrt

Then use <name>.com as input to Gaussian, then try the resp calculations
as above.

Admittedly, antechamber ought to give better error messages...we'll look into
that.

I can't be sure if this is your problem, but it is certainly something to
try.

..good luck...dac
