KAT and UKX

Some crazy schtuff here...

Anyone know why neither of these links work? Should be pretty popular, y'know.

Seen this link displayed many times, guess UDN doesn't allow just any eyes to see this tutorial? Nothing much else out there on UKX Authoring.

And I've also seen this link everywhere but for some odd reason, mathengine server is down. Anyone know why, perhaps?
