You get this once you have removed a library.
Looks like a combination of what cubase is saving with the cpr (which is not the actual vstsound but some copy of it it seems)
Once removed and you load a cpr that has references to an old deleted file it continues to look for the thing that was removed.
By the way, the library handling with H6 has become a real PITA.
With all those extreme naming and referencing conditions that have to be fulfilled it just gets more and more cluttered on the harddrive.
This is something that definitly has to be improved in the next update, since it is not even possible to make a very simple sound working in HS3 as it should. It did once, but then things got completely messed up…
