FCK Editor does not show the YouTube button

Hi all,

I have downloaded the youtube plugin from the source forge and extracted the same into the editor\plugins folder.

I then modified the fckconfig.js
FCKConfig.Plugins.Add( 'youtube', 'en,ja' ) ;

FCKConfig.ToolbarSets["Default"] = [
['Source','DocProps','-','Save','NewPage','Preview','-','Templates'],
['Cut','Copy','Paste','PasteText','PasteWord','-','Print','SpellCheck'],
['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
['Form','Checkbox','Radio','TextField','Textarea','Select','Button','ImageButton','HiddenField'],
'/',
['Bold','Italic','Underline','StrikeThrough','-','Subscript','Superscript'],
['OrderedList','UnorderedList','-','Outdent','Indent','Blockquote'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyFull'],
['Link','Unlink','Anchor'],
['Image','Flash','Table','Rule','Smiley','SpecialChar','PageBreak'],
'/',
['Style','FontFormat','FontName','FontSize'],
['TextColor','BGColor'],
['YouTube'],
['FitWindow','ShowBlocks','-','About'] // No comma for the last row.
] ;


But this does not show up the youtube button on the FCK Editor.

Can some one point me (kesavramesh@gmail.com) as to why the button does not shwo up?

I am using 2.X version
