Since the "Try EIAS3D" link takes you to the same "download" page as "Support/Downloads" does, my suggestion would be to remove it from the nav bar at the top of the site entirely as it's superfluous and misleading.
I've downloaded the program and installed both it and the OS X Universal Dongle Installer. Now what? It tells me that the "hardware key not plugged in".
So it's not a demo of the program?
I'm confused...
