  This now means that the optimization failed for some reason.
  There are many reasons this can happen, mostly having to do with
too-sparse or unusual data.  Without knowing anything about your data,
the one thing that pops out is you are using a binomial family with
zeroInflation=TRUE.  If your response is a matrix of successes and
failures, that's unusual but plausible; if your response is a single 0/1
vector, then it doesn't make sense to use zero-inflation.  (If your
response is anything else it's odd too, although that probably would
have been caught earlier.)
  Try working through the troubleshooting steps under ?admbControl (and
running with verbose=TRUE to see exactly what AD Model Builder reports
as the problem).
