can't offer much help, but have you tried to remove the ligand and try refinement? it would let you know if the pdb file or the presence of the ligand is the problem. at least let you would know where you should focus your attention.
if all else fails, have you tried getting parameters for your ligand from the PRODRG Server and using that for inputing the ligand parameters into phenix.refine directly when you setup the refinement job? (I think i have done this before???)
here is the website in case you aren't familiar...
Again, Best of luck!

Subject: [phenixbb] phenix.refine problems with my pdb
I am trying to run phenix.refine but I keep getting the message:
Sorry: Fatal problems interpreting PDB file:
Number of atoms with unknown nonbonded energy type symbols: 308
Please edit the PDB file to resolve the problems and/or supply a
CIF file with matching restraint definitions. Note that
elbow.builder is available to create restraint definitions.
I have run my ligands through elbow and used the output .cif but I
still get the same message. I can find no info on this problem in
the manual or the BB, can anyone help? Thanks in advance, yours, Matt.
