Vray for Sketchup crashing on one Sketchup File

Hey,
I have a problem with sketchup for Vray. It seems to only be with this one Sketchup file and when I go to open asset editor or interative render, it says - the new version 6 is available and then it crashes sketchup with this msg. I tried purging the unused and even copying into a new model but it does the same thing. Any ideas please?

Did you install the new update?

Yes, I’ve installed the update
