Urgent WordPress Automatic Upgrade Update

In case it helps, I just manually upgraded to WP 2.5 and when I click ‘Activate’ for this plugin now I get this:

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

Parse error: syntax error, unexpected $end in /path/to/my/webroot/wp/wp-content/plugins/wordpress-automatic-upgrade/wordpress-automatic-upgrade.php on line 1228
