Why you think you still have the old version ? How you did the update ?
If you haven't installed using the GSX full installer, but got the updates by installing either the Addon Manager or another FSDT installer, which migrated GSX in the new Addon Manager folder, you surely have all the latest files, because Live Update update them all. However, the version listed in the Windows Control Panel won't change, because that will only tell which installer you used to install it, originally.
