Installaion problem

Hi,

I just installed FCK Editor and when i tried to run it i get this message:
Not Found

The requested URL /fckeditor/editor/fckeditor.html was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

My code is in fckeditor folder on linux hosting and Here is my code:

   include_once("fckeditor/fckeditor.php") ;
   $oFCKeditor = new FCKeditor('FCKeditor1') ;
   $oFCKeditor->BasePath = '/fckeditor/' ;
   $oFCKeditor->Value = '<p>This is some <strong>sample text</strong>. You.</p>' ;
   $oFCKeditor->Create() ;

Thanks
