Response 403 in restricted download

Can you change the function in File.php in this way to have not 500 but 403 on restricted download?

function DownloadDenied($msg_id) {
		if(WPFB_Core::$settings->inaccessible_redirect && !is_user_logged_in()) {
			//auth_redirect();
			$redirect = (WPFB_Core::$settings->login_redirect_src && wp_get_referer()) ? wp_get_referer() : $this->GetUrl();
			$login_url = wp_login_url($redirect, true); // force re-auth
			wp_redirect($login_url);
			exit;
		}
		$msg = WPFB_Core::GetOpt($msg_id);
		if(!$msg) $msg = $msg_id;
		elseif(@preg_match('/^https?:\/\//i',$msg)) {
			wp_redirect($msg); // redirect if msg is url
			exit;
		}
		wp_die((empty($msg)||!is_string($msg)) ? __('Cheatin’ uh?') : $msg,"",array( 'response' => 403 ) );

		exit;
	}

500 is for error, this is restricted download and google sign this link as broken.
