ADDRESS 0x0921F945 HAS INITIATED PROGRAM ABORT BECAUSE OF FATAL ERROR(S)

My Input is as follows:

$CONTRL SCFTYP=MCSCF MPLEVL=2 RUNTYP=ENERGY
UNITS=ANGS COORD=UNIQUE ICHARG=0 MULT=1 MAXIT=50 $END
$SYSTEM TIMLIM=30000 MEMORY=8000000 $END
$BASIS extfil=.t. GBASIS=cc-pVDZ $END
$DATA
ccd XMCQDPT Ag Au Bu Bg cc-pVDZ

...
$END
$GUESS  GUESS=MOREAD  NORB=170 NORDER=1
IORDER(31)=31,37,39,32,33,34,35,36,38 $END
$MCSCF CISTEP=ALDET ntrack=10 $END
$DET NCORE=25 NACT=8 NELS=8 NSTATE=10 WSTATE(1)=1,1,1,-0 GROUP=C2h ISTSYM=2 $END  
$XMCQDPT KSTATE(1)=1,1,1,-0 ISTSYM=2 INORB=0 WSTATE(1)=1,1,1,-0 $END
$VEC
...
$END

Please advice on how to solve this problem. If there is anything wrong with my input that would also apply to the Ag symmetry, please let me know. The basis set was taken from the EMSL library

Also I'd like to report that ISTSYM=2 corresponds to the Bu symmetry unlike stated in the manual (according to which it should be ISTSYM=4 or ISTSYM=3 (in the example section))

Any help would be appreciated.
