Yes, the ambpdb worked previously on other prmtop files but started this
problem
when I used the new parameters in parm99.dat and created prmtop/crd files
with tleap.

Sorry for that, as I am using leaprc.ff99SB with parm99 and that one using:
PARM94 for DNA, RNA and proteins with TIP3P Water. USE SCEE=1.2 in energy
progs
and I get no errors when I use it with FAD.mol2
but the problem I am facing now with ambpdb
I also checked on just fad and there is a strange character 'Y' in the
output pdb:
-bash-3.2$ ambpdb -p fad.top < fad.crd
| New format PARM file being parsed.
| Version = 1.000 Date = 11/30/09 Time = 19:27:07
REMARK
ATOM 0 Y FAD 4 0.000 0.000 0.000
ATOM 1 O3B FAD 4 58.127 139.363 12.551

.............the rest is ok.
