So I take 'ol Steven up on his offer for his CLA mixing course.
They offer the project up in quite a few DAW formats. For me that means Reaper, Studio One 3 and SOANR.
Go ahead and take a guess which project will not open properly? No, not Reaper and not SO3.
Yup, SONAR reports that Slate's VMR is not found. Yet, after the project is open I can insert VMR anywhere I want, successfully.
So I look at the class ID for VMR and I search the registry for classID and guess what? It's found. Do you know what the classID is for? Yup, you guessed it.... VMR. What The Bloody Hell?
I submitted a problem report to both CW and Slate.
Maybe I should just spend the $5K and go to Wavesland for vacation this year.
<edit> Footnote: any project of mine where VMR resides opens just fine.
