I've installed membership and I am in the process

Hi

I've installed membership and I am in the process of setting it up. When I add the membership login widget to the sidebar I get the following error message [which can be seen on the site members.ladyarse.com]

Fatal error: Call to undefined function do_shortcde() in /homepages/43/d336386751/htdocs/members-la/wordpress/wp-content/plugins/membership/membershipincludes/addons/login.widget.php on line 44

I've tried other themes, deactivating other widgets etc. Any help would be great, thanks.
