Caterpillar Script Error

[Ace]

I am not a scripter but paste this in main:

Content Hidden

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

begin
# Prepare for transition
$defaultfontface = "Tahoma"
$defaultfontsize = 24

Graphics.freeze
# 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

I didn't get any error but my main looks also like this, so try it^^
