Error in X-HCFF and CPCM calculations

Questions
#1

Dear all,

I ran single point calculations with X-HCFF and CPCM on Qchem 6.0.0. The jobs fail right after the SCF Convergence criterion met. The error message I got is " Q-Chem fatal error occurred in module libmdc/newfileman.C, line 376:

FileMan error: End of file reached prematurely reading (54360) bytes in file FILE_PCM_NUKE_ESP."

Parts of input files are as follow:

$rem
JOBTYPE FORCE
METHOD TPSSh
UNRESTRICTED TRUE
SCF_MAX_CYCLES 450
SCF_CONVERGENCE 7
XC_GRID 1
BASIS Gen

SYM_IGNORE TRUE
SYMMETRY FALSE

use_libqints true
gen_scfman true

molden_format true
$end

$distort

$end

$end

$solvent

$end

What is making the error here? Thank you in advance for your help!

Do you know for certain that PCM is compatible with this method? What does the manual say? In general it is helpful if you can find a minimal example that fails, getting rid of extraneous $rem and $pcm variables.
