Justin,
All the directives are correct. Chris just mistyped saying
[ molecules ]
CIP 3
instead of
[ moleculetype ]
CIP 3
that I orginally send him.
He can't know how many CIPs I have in my system because I didn't send
him this section. :)
You said before:

Only once."
Does this mean you have only one solute? Or that you have only one entry for
solute, which you then have multiple molecules of in the system? There
certainly can be confusion if you aren't describing your system clearly.
The reason for asking is that the problematic atom numbers (which are greater
than 42, as Chris pointed out) would indicate one of two possibilities:
1. CIP is present multiple times, and one of those molecules (at least) is
having a problem.
2. There is one CIP, it does not appear as the first molecule in the system (due
to the numbering), and perhaps (as I suggested) there was some sort of incorrect
order.
If neither of these is true, then it is important to know.

There's your problem (although in a different manner than I thought).
If you have, for example, 3 solutes, then you should have
[ molecules ]
CIP 3
-NOT-
[ molecules ]
CIP 1
Of course, the number of moleules in .top and .gro files coincides.
Otherwise, one would have had immediate crash.
CIP 3 -> [ moleculetype ] !
[molecules] is a different directive than [moleculetype]. Under
[moleculetype] you find the name of the molecule and the number of
exclusions, not the number of molecules. Do you have only one solute? If
so, then it cannot be the first molecule in the system, given the atom
numbers in the crash you reported before. Is everything in the [molecules]
directive in the same order as your coordinate file? Did grompp give any
atom type mismatch warnings?
