For the downloads script i found i wan't to sumbit an addon but to do that i need to go to my mysql manager and execute this query:

CREATE TABLE download_comments (
comments_id int(10) NOT NULL auto_increment,
file_id int(10) NOT NULL default '0',
comments_text text NOT NULL,
comments_poster text NOT NULL,
comments_ip text NOT NULL,
comments_title text NOT NULL,
comments_time int(50) NOT NULL default '0',
PRIMARY KEY (comments_id),
KEY comments_id (comments_id)
) TYPE=MyISAM;
