Change Rev-X reverb type without Cubase

My mr816x comes with Cubase AI 4, but the new MR Tools don’t support it anymore. I am trying to find a way to change the rev-x reverb type outside Cubase, but no joy. Any suggestions?
Thank you

An update - seems like the VST plugin for rev-x is not working, too. It shows in Cubase AI4 but wont load.

The reverb type can be changed in the EXT FX section with clicking on the text label. It is far from obvious - why this is not in the reverb effect panel itself!?
