MySQL Error on /station/programs - Unknown table

Hi there,

i've got a mysql error on the url /station/programs ...
maybe i do/did something wrong, but i tried the 'stable' version and the dev version. both comes with this error.

    * user warning: Unknown table 'radio_station_schedule' in where clause query: SELECT count(node.nid) FROM radio_node node LEFT JOIN radio_station_schedule station_schedule ON node.nid = station_schedule.program_nid LEFT JOIN radio_station_program station_program ON node.vid = station_program.vid WHERE (node.type IN ('program')) AND (node.status = '1') AND (radio_station_schedule.program_nid IS NOT NULL) in /home/radio/domains/MYDOMAIN.com/public_html/includes/database.mysql.inc on line 172.

    * user warning: Unknown table 'radio_station_schedule' in where clause query: SELECT node.nid, node.title AS node_title, node.changed AS node_changed, station_program.genre AS station_program_genre FROM radio_node node LEFT JOIN radio_station_schedule station_schedule ON node.nid = station_schedule.program_nid LEFT JOIN radio_station_program station_program ON node.vid = station_program.vid WHERE (node.type IN ('program')) AND (node.status = '1') AND (radio_station_schedule.program_nid IS NOT NULL) ORDER BY node_title ASC LIMIT 0, 50 in /home/radio/domains/MYDOMAIN.com/public_html/includes/database.mysql.inc on line 172.

i took a look in the mysql database and the tables are present, so what's the error?

Thanks

Andreas
