there are some parameters in NAMD which cannot be changed once a run
begins; pairinteraction is one of them (others include things like
annealing options). So the problem here is that you've already run
100000 steps, and then try to turn on pair interactions after that.
Things should work fine if you just split these up into separate runs
and then use the restart files from the equilibration to start your pair
Also, you may want to make sure that the "Pair Interaction parameters"
line is commented out; it probably was in your actual file but does not
appear to be in the email.
