reactivation pro version from old subscribe

Hello,
in 08.14.2012 ive bouoght a pro version of this reservation system and ive got a zip file with plugin, when i upload and activate it on wp there are some errors. So ive downloaded the last update from here and just added a pro.php file and i think its working but at orders columns is an error Warning: Missing argument 2 for wpdb::prepare(), called in /data26/equipark/html/wp-content/plugins/wp-reservation/wp-res-pro.php on line 1517 and defined in /data26/equipark/html/wp-includes/wp-db.php on line 1209. Is it possible to fix that? And also is there any way how to start translation to Czech language? Thanks
