Hi there,
Bear in mind that the game does not auto-update, you have to trigger the update yourself. If you hit the big Play button, then you should see "Found X beta updates," where X is some number (probably 1). Once you click that and go through the update process, you'll be on the latest version. If it's not showing that "found beta updates" button, then there's a firewall blocking the game from checking with amazon s3, and you'll want to allow the game to access the Internet on your local firewall.
Hope that helps, and thanks for your support!
