[Plugin: Query Multiple Taxonomies] Fatal error with blog creation

I am getting this error while creating blogs with wpebooks.com/replicator/

Fatal error: require(): Cannot redeclare class qmt_terms in wp-content/plugins/query-multiple-taxonomies/query-multiple-taxonomies.php on line 34

If its ok for you, can you change require with include_once or something?
