Sharing a Cubase project.

hello…my first post here…

I tried sharing a whole cubase project with another (via drop box)
(He edited my full mix and sent my whole project folder back)
We both have all the same plugins.
All worked fine but I noticed that all the projects VTS plugins( eg: waves) go back to their ‘default’ position.
All other project changes where ok (automation, levels, Cubase plugins)
Anyone know why?
Thanks :slight_smile:
