need help getting sounds/effects back

I had to do a total rebuild. Windows 10 pro, then bought Cubase 9. I am missing plenty of stuff, most notably are the Halion Trip, several of the SE plugs, and the convolutions for Reverance. Can anyone help me to get this stuff? Last time I did a full re-install was 3-4 years ago, and it was a huge pain. I lost a week of work, and my back is against the wall.
Thanks much

Not sure if you ever solved this but I had exactly the same problem until last night when I downloaded Cubase 9 and installed from scratch. Seemed to fix everything.
Now all I have is some missing soundsets that Steinberg doesn’t seem to have downloads for! But that’s a story for another post!
