Thayna,
I now know what happened to your case. Just comment line 286 in readnml.f90 and line 447 in chkwrfhdr.f90 which perhaps unnecessarily restrictive. Then try to run mcip again after recompile its source code.
! CALL graceful_stop (pname)
Do not forget to correct line 759 of the ctmproc.f90 routine according to Mcipv5.0 bug detected
