Using Geo Data Store Plugin Code

I deleted the Geo Data Store plugin and reinstalled, in which my code worked upon refresh. I was able to use the functions from the plugin and so on. I casted as an array so as to use the output in my wp_query arguments

$sc_gds = new sc_GeoDataStore();
$ids = (array) $sc_gds->getPostIDsOfInRange( $type, $radius, $lat, $lng );
$args = array('post__in' => $ids, 'post_type' => 'custom_post_type');
