Database Error after Upgrade to 3.5

I just upgraded to 3.5 and found this error on my catalog page

\\
Warning: Missing argument 2 for wpdb::prepare(), called in …/wp-content/plugins/sc-catalog/sc-catalog-data.php on line 121 and defined in …/wp-includes/wp-db.php on line 990

sc-catalog-data.php line 121 is:
. ” ORDER BY disp_order” );

wp-db.php line 990 is:
function prepare( $query, $args ) {
if ( is_null( $query ) )
return;
\\

Any it ideas on what is now missing after the update or if there is a conflict somewhere?
