 Hello
  you are heating the protein too fast!! Did you add the tcl libraries to
  your namd installation?
  What does your config file look like? Then I can tell you if there is
  something wrong with your config.
  I will bet that you have an unkown
  command error in your log file just above the errors you list below.
