Well, I e-mailed him "later," it just wasn't that day. Sorry for the delay.
He says that he took the links down after discovering that someone had hacked the registration code, and suddenly no one was buying it. He's busy at the moment with endeavors that actually pay (in his words), and therefore hasn't had a chance to fix it.
It's curious that the hack would cause sales to stop. There certainly has been no public evidence in the forums, especially the Prius forums where the simulator would be most popular, of mass illegal use. And I believe the integrity among forum members would bring to a halt any wholesale attempt to distribute the hack covertly. So most forum members interested in getting the application (like you) wouldn't be aware of the hack and would still take the legit purchase route.
