Or you need to import the correct matching database data, since what you've got in the database presently isn't suitable for your current DB_PREFIX configuration.
(To manually figure out the correct prefix to use, look at the database using phpMyAdmin and see what common 2-4 letter prefix starts all the tablenames. Then set that value into the DB_PREFIX definition in your configure.php file.)
