Mircea, you want to run Couatl_Updater rather than Couatl_Updater 2 because Couatl_Updater will check first to see that Couatl_Updater2 is up to date, and once it does that, it'll run the update. If you run Couatl_Updater 2, it might not actually be up to date. That being said, when you run an update, it'll check the files to see if anything needs to be updated, and it'll update files accordingly. If you're up to date, it just won't update any files.
