eRROR can't find the commentform id div ?

[reboltutorial]

I have installed subscribe to threaded comment plugin and follow the instruction
http://wordpress.org/extend/plugins/.../installation/

But when clicking on reply
http://reboltutorial.com/blog/reflection/#comment-437

it says
can't find the commentform id div ?

Am I missing something or is it a bug ?

Never mind will delete this plugin and find another one.
