Hmm. I had this problem last week with waves v8 demo.
I ended up reinstalling them and it worked fine.
PT9 showed 'loading waves v8.0.0 waveshell' but the plugs weren't in my lists until after a reinstall.
Try that and see what happens.
If memory serves, the little dialogue says "check the plugin type you don't want to use", so I just don't check anything.
This is fine.
