Fatal Error Message - I think when I installed Marketpress eCommerce ...

Hi, I get this error message when my site loads: Fatal error: 'continue' not in the 'loop' or 'switch' context in /homepages/20/d612269631/htdocs/clickandbuilds/WordPress/Women_Partisans_Soldiers_and_The_RIghteous/wp-content/plugins/marketpress/includes/common/payment-gateways/payfast.php on line 180

What should I do?

By the way I can't get to the dashboard to grant you access.

Thanks - John
