Forum hack please help

[Rizzler]

Hello

I had my forum hacked today and the frontpage defaced. Any file i try to go to gives me the hackers message on the front i removed every file on the server and reuploaded them, set the config.php with the database information and also added define('DISABLE_HOOKS', true); into the PHP, now after i did this there was no change, the hackers message is still in the database wich makes me guess that he maybe changed FORUMHOME as suggested when i tried searching google for answers, i can access the database from Phpmyadmin BUT i cannot access the forum adminCP i can access the login windows but when i press "login" it redirects me to login.php wich gives me the hackers message again, what do i do from php my admin to get my forums back online ?
