[Plugin: Popularity Contest] Unable to activate in WordPress 3.0.2

Hello,

I am running the latest version of WordPress (3.0.2) on a local server. I want to try/use Popularity Contest plugin, but each time I attempt to active it, I have an error message which says:

Plugin could not be activated because it triggered a fatal error.

Incorrect table name '' on line: 255

Here is the function written in these lines:

$result = mysql_query("
			CREATE TABLE <code>$wpdb->ak_popularity_options</code> (
				<code>option_name</code> VARCHAR( 50 ) NOT NULL,
				<code>option_value</code> VARCHAR( 50 ) NOT NULL
			)
		", $wpdb->dbh) or die(mysql_error().' on line: '.__LINE__);
		if (!$result) {
			return false;
		}

I can also tell you that my MySQL settings look like this:

/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

Your help will be much appreciated — do you have any ideas?
