Cant install my Magic SEO unless I DL Zend Guard

[Rheon]

Hi all,

I'm having a problem installing my SEO, I am getting this issue on the top of my site.
Anybody know of a work around to disable the zend guard so that I can install my SEO?

This is the code I am inserting, the same code is prompting me to DL zend guard:

include(DIR_WS_INCLUDES . 'magic_seo_url.php');
$current_page_base = $current_page = $_GET['main_page'];
$page_directory = $code_page_directory = DIR_WS_MODULES . 'pages/' . $current_page_base;
include(DIR_WS_INCLUDES . 'init_includes/init_category_path.php');

Thought please.....................
