Before you jump to any conclusions about the machine not working make
sure that the cord's plugged in. Did you forget a weighting term or
did listwise deletion dump most of your cases? Standard errors of
these cutoffs should be proportional to 1/sqrt(n) and these are huge.
Usually what happens with a crappy model is that the terms end up not
separated, but that's not what you have here.
