Wavelab v6.10 working with Waves Gold v7r16?

I can’t get these two to work together. Wavelab continues to reject with error “Waveshell-VST 7.1.dll cannot be loaded” . I know both are a slightly dated, but then so am I. Has anyone had success with these two? I have already spent massive amounts of time trying to work this out with Waves techs.

I will try Wavelab 6.11 (build 353) and see if this helps. I will post results.
