Cubase 10 pro upgraded from Artist 10

I did an upgrade from Artist 10 to Cubase Pro 10.0.30 and now Cubase doesn’t recognise any of my Toontracks plugins. I have uninstalled all of them and reinstalled but still having the problem. I have also uninstalled Cubase 10 and reinstalled it but again the same problem exist. I am now at a loss as to what to do about it. I have spoken on the phone with support but they offered no help. just said to uninstall and reinstall. Anyone else dealing with these issues or know of anything else to try?

Check the path of your Toontrack PlugIns in the PlugIn-Manager.
