Unable to view Manage Events page

I'm encountering a "The page cannot be displayed because an internal server error has occurred." when I attempt to view the Manage Events page from the jEvents Dashboard. The url for the page ends with 'index.php?option=com_jevents&task=icalevent.list'

Any thoughts on how I can clear this error and get to the page to be able to manage the event listings?

Thanks for any help!
