You set the table prefix in your bb-config.php to wp_? That would almost certainly overwrite your wp_tables then. Restore from a backup and start over. You need to add the secret line to your wp-config.php and bb-config.php both.

If you have access to phpMyAdmin (looks like you’re at 1&1 Internet? They have phpMyAdmin installed in the control panel) take a look at the database tables directly and see what happened. Looks like you don’t have a wp_users table any more, and looking at the database directly will confirm if that’s the case.
