Exporting importing issue with wp_bdprss_items table

I am in the process of moving hosting providers.

I have been able to export and import all of my websites and now I am in the processes of moving my biggest and last one.

When I try to import my db I am able to import every table expect for one.

I get the following error:

CREATE TABLE wp_bdprss_items (
item_feed_url varchar( 240 ) NOT NULL default ”,
item_url varchar( 255 ) NOT NULL default ”,
item_name varchar( 255 ) NOT NULL default ”,
ref_number int( 5 ) NOT NULL default ‘0’,
text text NOT NULL ,
item_time int( 15 ) default NULL ,
item_update_time int( 15 ) NOT NULL default ‘0’,
PRIMARY KEY ( item_feed_url , item_url ) ,
KEY feed_index ( item_feed_url ) ,
KEY update_index ( item_update_time ) ,
KEY time_index ( item_time )
) TYPE = MYISAM ;
