CCL:G03 PCM Error



Colleagues,
 Occasionally when running a G03 pcm calculation on a molecule I get an
 abnormal termination with an error message like the following.
  United Atom Topological Model (UA0  parameters set).
  UA0: Hydrogen    5 has 3 bounds. Keep it explicit at all point on the
  UA0: potential energy surface to get meaningful results.
 Can anyone tell me how to fix this problem?  How do I keep an atom
 explicit?
 Thanks,
