Are you looking for any version in particular? The latest 3.3 version can be grabbed here, for example (if you have V3 access): https://www.ephere.com/plugins/autodesk/max/ornatrix/3.3.3.0.0.single.install
You can change the version/build number in that link if you know the exact one. I'll see if we can add web access to these archives to make it easier.
