G94: frequency calculation

 Hi, there,
 I'm wondering if the frequency calculation in g94 must be performed in the
 second step of the calculation. If I have the check point file, can I do a
 separate frequency calculation (without optimizing the structure again
 because it takes too long). I used the following lines in my .com file and
 the program stopped  short after it started because of "Error termination
 in NtrErr: NtrErr called from FileIO":
 $ RunGauss
 # HF/LANL2DZ Freq=(ReadFC, ReadIsotopes) Geom=AllCheck Test
 Thank you for your time and help.
