Warning message from WP 3.5

I’m getting something similar

Warning: Missing argument 2 for wpdb::prepare(), called in /../../public_html/wp-content/plugins/wp-e-commerce-bulk-category-pricing/wpec_bulk_cat.php on line 146 and defined in /../../public_html/wp-includes/wp-db.php on line 990

any help would be appreciated like the poster above me have also had to disable, checked the two files mentioned and can see nothing wrong in comparison to my backups.

Thanks
Tom

Finally I solved the issue.
It’s because of the security warning from wordpress 3.5 for using wpdb method in insecure way.
What I do is in wpec_bulk_cat.php, try to search$bulk_categories = $wpdb->get_col (&wpdb->prepare("SELECT object_id FROM“.WPSC_TABLE_META.”WHEREmeta_key` = ‘use_bulk_pricing’ AND meta_value = 1″ ));
change the whole line to
$bulk_categories = $wpdb->get_col(“SELECT object_id FROM ".WPSC_TABLE_META." WHERE meta_key = ‘use_bulk_pricing’ AND meta_value = 1″ );`

Then everything backs to normal

Thanks so much worked like a charm!
