[Plugin: BFT Autoresponder] Database Error

Hello there,

Just tried installing the BFT autoresponder plugin on two different sites, with two different hosts, yet I get the same error on both of them:

WordPress database error: [Table 'database.wp_bft_mails' doesn't exist]

And bellow that a different error depending on the plugin page, like
INSERT INTO wp_bft_mails (subject,message,days,send_on_date,date) VALUES ("dasd","asadsadsdas","",'1','2012-04-17')

SELECT * FROM wp_bft_mails ORDER BY days

Etc.
How can this be fixed?

Regards,
Tiago
