If you've cleared your cache like Lukzmm suggested, then I don't know what else to tell you. If you open the Play PTD! page and hit ctrl + f5 until the game has to reload (i.e. it does not immediately show up), then you have cleared it from your cache and it should download the version hosted on the site.
