Warning in IE 8 after implementin piwik analytics (no replies)

Hi,
We recently implemented piwik in our application.
Everthing is working fine except the following error-->'Internet explorer has blocked this website from displaying content while loading'.

This message is shown when the piwik.js is loaded and is appearing only in IE.
Also note, that our piwik server is on a different machine than our application's.

Im guessing this might be due to expired certificate on piwik server.
Any workarounds to get past this error??

piwik version- 2.3.0
Tracking code-->
var siteId="<%=siteId%>";
var _paq = _paq || [];
_paq.push(['trackPageView']);
_paq.push(['enableLinkTracking']);
(function() {
var u=(("https:" == document.location.protocol) ? "https" : "http") + "<%=piwikUrl%>";
_paq.push(['setTrackerUrl', u+'piwik.php']);
_paq.push(['setSiteId', siteId]);
var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0]; g.type='text/javascript';
g.defer=true; g.async=true; g.src=u+'piwik.js'; s.parentNode.insertBefore(g,s);
})();
