How do you know it failed?

As far as I know, the perl version of the script does not print out the
final binding free energy numbers; just the decomposition. Furthermore,
simply summing TGBTOT will not give you the total energy, I don't think.
The issue that you have is that inter-residue, non-bonded interactions are
included in both residues. You could write a small awk script to pull out
the necessary values from the output files (if you kept them via the
"verbose" keyword in the input file).
If you have Amber11, MMPBSA.py provides decomposition functionality and
prints out a decomp summary as well as a final binding energy summary as
well. It also simplifies the input procedure (so it figures out recmap,
ligmap, etc.).
Hope this helps,
Jason
