gaming Looking for an old game

[Silly Druid 7,045]

It's a game called Aargon Deluxe (the PC version). It's a puzzle game about manipulating laser beams. What I need is a version of the game that contains the last 2 level packs: the spooky-themed one, and the medical-themed one. I can download the demo from the creators' website ( http://www.twilightgames.com/ ), but clicking on "buy" from within the game doesn't work (it takes me to a page that doesn't exist), and the contact email doesn't work either.

If you know how to get the latest version of this game, please post here or send me a message.
