If you are using a spring (body-body or to ground) as defined under connections and then suing the preload under the details of the spring and then do as shown in the video, then that works. I would suggest, that you make a small test example say with one cube and one body to ground spring that is not active in 1st step and then active in second, and that has the preload.
