Please I need your help with sna4elgg

I installed elgg2.3 and sna4elgg 2.2 and everything is ok and I can download the file graph.gexf but when I open this file with an editor of text, it only has this: 
<!DOCTYPE html>
        <meta charset="UTF-8" />
        <meta http-equiv="refresh" content="0;url=http://elicinet.campus.utm/admin/administer_utilities/sna4elgg&quot; />

        <title>Redirecting to http://elicinet.campus.utm/admin/administer_utilities/sna4elgg</title&gt;
        Redirecting to <a href="http://elicinet.campus.utm/admin/administer_utilities/sna4elgg">http://elicinet.campus.utm/admin/administer_utilities/sna4elgg</a&gt;.
