Caterpillar Script Error

[konterganon]

i just got the error again, this time it happened in the middle of a battle, no one died. it happened just before the execution of a skill.

this is a screenshot of the message:


would it somehow be possible to disable the whole caterpillar script upon the start of the battle scene?

Edit:
uhh.. now i get the same error but elsewhere...in MAIN oO


my main looks like this:

Code:

#==============================================================================
# ** Main
#------------------------------------------------------------------------------
#  After defining each class, actual processing begins here.
#==============================================================================

begin
  # Prepare for transition
  Graphics.freeze
  $defaultfontface = "Tahoma"
  $defaultfontsize = 24
  # Make scene object (title screen)
  $scene = Scene_Title.new
  #Scene_Movie.new("tis")
  #Scene_Movie.new("intro")
  # Call main method as long as $scene is effective
  while $scene != nil
    $scene.main
  end
  # Fade out
  Graphics.transition(20)
#rescue Errno::ENOENT
  # Supplement Errno::ENOENT exception
  # If unable to open file, display message and end
# filename = $!.message.sub("No such file or directory - ", "")
  #print("Unable to find file #{filename}.")
end
