Sale offer ads error

When I click on my sales ad, I get the following error:

WordPress database error: [Unknown column ‘robot’ in ‘field list’]
INSERT INTO wp_prli_clicks (link_id,vuid,ip,browser,btype,bversion,os,referer,uri,host,first_click,robot,created_at) VALUES (2,’irhv7j’,’189.216.191.251′,’Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 GTB7.0 (.NET CLR 3.5.30729)’,’Firefox’,’3.6′,’WinVista’,’http://www.dogtraining-courses.com/’,’/secrets’,’customer-189-216-191-251.cablevision.net.mx’,0,0,NOW())

It worked fine before, and I don’t understand a thing about this error.

Any help, please?
