I am assuming Step 1 has an misatke in the read me?
Read me contains below.

Step 1.

In class_core.php ;

Find ;

		// fetch client IP address
		$registry->ipaddress = $this->fetch_ip();
		define('IPADDRESS', $registry->ipaddress);

		// attempt to fetch IP address from behind proxies - useful, but don't rely on it...
		$registry->alt_ip = $this->fetch_alt_ip();
		define('ALT_IP', $registry->alt_ip);


Replace with ;

		// Paul M - Get ip addresses.
		$registry->ipaddress = $this->fetch_ip();
		$registry->alt_ip = $this->fetch_alt_ip();

		// Check that alt_ip is valid address, reset to original if not.
		if (preg_match("#\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}#", $registry->alt_ip, $iplist))
		{
			$registry->alt_ip = $iplist[0]; 
		}
		else
		{
			$registry->alt_ip = $registry->ipaddress;
		}

		// Set ip constants.
		if ($registry->ipaddress == $registry->alt_ip)
		{
			define('PROXYIP',''); 
			define('ALT_IP',$registry->alt_ip);
			define('IPADDRESS',$registry->ipaddress);
		}
		else
		{
			define('ALT_IP',$registry->alt_ip);
			define('IPADDRESS',$registry->alt_ip); 
			define('PROXYIP',$registry->ipaddress);
			$registry->ipaddress = $registry->alt_ip;
		}

Closing curly bracket is not supposed to be there? Well it errored for me unless i removed it.
