the error is due to your choice of basis set which is inconsistent.
You are asking for sto-2G(d) basis set for Ag which is nonexistent.

 $BASIS  GBASIS=STO NGAUSS=2 NDFUNC=1 POLAR=POPN311 $END

I'd suggest you to try ECP basis sets first, e.g.
to request SBK plus a single additional d function:

 $CONTRL ecp=sbk mult=2 scftyp=uhf DFTTYP=B3LYP RUNTYP=OPTIMIZE $END
 $SYSTEM TIMLIM=100000 MEMORY=10000000 $END
 $BASIS  GBASIS=Sbk NDFUNC=1 POLAR=POPN311 $END
 $STATPT HSSEND=.T. NPRT=-2 NSTEP=500 OPTTOL=0.0001 $END
 $FORCE NVIB=2 VIBSIZ=0.005 $END
 $DATA
 Ag3
Cnv       2

SILVER     47.0      1.591769840         0.000000000         0.794705433
SILVER     47.0      0.000000000         0.000000000        -1.589410866
 $END

I have fixed several additional errors in your initial input.
You can find this input file and an output file in the attachment.

Kind regards,
