Integrate the Crop2Size Plugin

Hi,

I bought a license of Crop2Size FCK Plugin yesterday and I cannot add the button to the FCK Toolbar.

Step 3 in the install doc is;

# Open the FCKeditor/fckconfig.js file in a text editor.
# Add the following line to the fckconfig.js file:
   FCKConfig.Plugins.Add( 'crop2size' );
# Add Crop2Size™ to your current ToolbarSet by inserting 'crop2size' into the toolbar. See the FCKeditor documentation at http://wiki.FCKeditor.net/Developer's_Guide/Configuration/Toolbar for more details. 

But, it don't works, the button don't show up on my custom toolbar, nor the "Default" one.

I have this in my fckconfig.js:

FCKConfig.Plugins.Add('crop2size');

...below the line FCKConfig.PluginsPath = FCKConfig.BasePath + 'plugins/' ; and my custom toolbar looks like this:

FCKConfig.ToolbarSets["Basic_Ext1"] = [
   ['Source', '-', 'Bold','Italic','Underline','-','TextColor','BGColor','-','Image','-','Link','Unlink','-','OrderedList','UnorderedList','-', 'FitWindow', '-', 'Crop2Size', '-', 'About']
] ;

I really need some help with this, I'm sure it's a "FCK issue", because Crop2Size works "Standalone".

Thank you!
