I believe you are correct that it is not available at this time. An earlier post from the developer stated that the initial release for FSX would be followed by an UK enhanced version and last an enhanced FS9 version with the new AI traffic feature. As for purchasing your license key from the rcsimulations website just click on the "order info" button on their home page and then click on the link to "secure on line order." I received an email with the key within 24 hours of submitting my order. Hope your version comes out soon.

Uggg I guess that means the updated FS9 version is a year or so away. I've fiddled with the VoxATC X demo a bit and I love the improvements over the vanilla US FS9 version but given FSX's poor performance on my machine I won't be making the jump to FSX for quite some time.
