Gaussian errors like this indicate missing information in your input or
checkpoint file.

In this case I am guessing it is because you specify "geom=connectivity"
but have not put a connectivity section in your input, you only put the
geometry.

Now you may say "it has worked before!" and I say "welcome to the
wonderful world of gaussian input files!".  I say this because the
connectivity section of an input file can be *empty* and gaussian will
detect this depending on the number of empty lines after the geometry!
So simply adding a few blank lines to the end of your input file can be
the difference between a failed or successful calculation.
