FabFilter

After having to purchase a new computer, I installed and authorised the fab filter bundle on the new machine. When I open projects that have instances of the plugs, Cubase says they are missing. I can open the plugs as though I'm inserting them for the first time, however all the settings will be different.

In short, the filters will load if I open them on the new computer, but will not find them with projects brought across from my old computer. All other reinstalled software is working.

Any ideas of how to get the new system to load the filters on opening a project?

Thanks for your thoughts...
