iCal Export Blank - new site

I have a site with Drupal 6.2 running Calendar 6.x-2.4, the Calendar works fine as I've entered in a year worth of data to it and it shows well, however the iCal export feature sends out a blank file. I am attaching a screen shot of the view settings I have for the iCal display as well as the live preview looks like:

BEGIN:VCALENDAR
VERSION:2.0
METHOD:PUBLISH
X-WR-CALNAME: | Student Housing
PRODID:-//Drupal iCal API//EN
END:VCALENDAR

Query	

SELECT node.nid AS nid,
   node.title AS node_title,
   node_data_field_event_date.field_event_date_value AS node_data_field_event_date_field_event_date_value,
   node_data_field_event_date.field_event_date_value2 AS node_data_field_event_date_field_event_date_value2,
   node.type AS node_type,
   node.vid AS node_vid
 FROM node node 
 LEFT JOIN content_type_calendar node_data_field_event_date ON node.vid = node_data_field_event_date.vid
 WHERE ((node.status <> 0) AND (node.type in ('calendar')))
    AND (DATE_FORMAT(ADDTIME(FROM_UNIXTIME(node.changed), SEC_TO_TIME(-25200)), '%Y-%m-%d') >= '2011-05-05')
   ORDER BY node_data_field_event_date_field_event_date_value ASC

Any help would be greatly appreciated. I have looked through the other threads that seem to indicate similar issues, but mostly with different versions of Drupal, however I didn't see anything that they've done that I haven't tried yet.
