I'm happy to report that 3DRad v7.22 is now completely free,and that the official 3DRad User Forum is back online. All this at http://www.3drad.com/ . Thank you, Fernando.
I've uploaded my saved .dat files for each of the six steps, so you should be able to get to the Grand Finale if you have not done so already. Get them from the MeccanoRAMA page.
