[PyMOL] APBS plugin woes

I download and install macpymol-1_2r2.tgz.

I make a copy of MacPyMOL.app and rename it PyMOLX11Hybrid.app and fire it up.

Load a pdb file after removing HETATM lines.

Open APBS Tools and set grid:
Log:
Maximum number of grid points exceeded.  Old grid dimensions were 
[129, 97, 129]
Fine grid points rounded down from [117, 87, 117]
New grid dimensions are [97, 65, 97]
  APBS Tools: coarse grid: (76.908,61.259,77.489)
  APBS Tools: fine grid: (65.240,56.035,65.582)
  APBS Tools: center: (-22.620,-1.106,-3.967)
  APBS Tools: fine grid points (97,65,97)

Click "Run APBS", see hydrogens appear, see residues being selected 
and unselected, then the display says:

Log:
ObjectMapLoadDXFile-Error: Unable to open file!
ObjectMapLoadDXFile: Does 'pymol-generated.dx' exist?


Help?
