I’m confused frustrated

How do I reactivate Orchestral Companion Strings Woodwinds and Brass and Big Bang 2 after upgrading to macOS High Sierra

After upgrading to macOS High Sierra when I launch any of these Sonivox products in Logic Pro X the GUI comes up but it will not make any sound or when I try to load a preset it ends up saying it can't find the samples even if I direct it right to the samples.
