[Plugin: Spreadsheet] empty page

I have the same problem.
I’m trying to install the plugin in a localhost wordpress but when i put shortcode i see an empty page. in the code of the page there is the spreadsheet <div> but it’s empty.
I had read the faq and the installation page.
i tried to put this code in the header.php file of my theme but doesn’t work.

<script src='https://localhost/wp-content/plugins/spreadsheet/codebase/spreadsheet.php?load=js' type='text/javascript' charset='utf-8'></script>
<link rel='stylesheet' href='https://localhost/wp-content/plugins/spreadsheet/codebase/dhtmlx_core.css' type='text/css' charset='utf-8'>
<link rel='stylesheet' href='https://localhost/wp-content/plugins/spreadsheet/codebase/dhtmlxspreadsheet.css' type='text/css' charset='utf-8'>
