Neo ABS loading bug

[gameline]

Hello everybody.
I have a problem with the Neo ABS script.
Every time that I load saves I get a strange error:

These are the lines:

  def read_save_data2(file)
    $NeoABS             = Marshal.load(file)
    # Change Animation Size
    for an in $data_animations
      next if an.nil?
      frames = an.frames
      for i in 0...frames.size
        for j in 0...frames[i].cell_max
          frames[i].cell_data[j, 1] /= $NeoABS.animation_divide
          frames[i].cell_data[j, 2] /= $NeoABS.animation_divide
          frames[i].cell_data[j, 3] /= $NeoABS.animation_divide
        end
      end
    end
  end
end

How can I fix it?
