Vray has encountered an error while trying to render.....etc....I rendered the same image minutes before, I just changed the materials and all of a sudden Vray does not render....
When I export all components without textures and materials, the same error!

does anybody know what this message means?
really, I´m loosing my mind with that problem!
I really would be so much appreciated if anybody could help me!

Geetings,

did you save your file, close completely out of sketchup (no other windows of sketchup open) Then open back up and try rendering again? Sometimes the vfs cache gets corrupted and you need to close out and try again.
