Error Showing on IE 8

I am seeing the following error with IE8 but not under Firefox, Safari or Chrome

Can you advise what to do to correct it as I do not want IE users seeing errors on a hosting site

Thanks

Alan

You can disable it in template_css_ie78.php

comment: behavior: url(templates/hot_host/css/PIE.php);

Thanks - that fixed the issue.

I also found if I downloaded the latest version of pie.htc the problem was also fixed
