Installed your plugin and it somehow messed up the material link when you pick a material from sketchup model it doesn't reflect on the vray material editor, the selection in the vray material editor is always stuck on 1 material, tried uninstalling the ruby by deleting the files and folder in the sketchup root folder then uninstalled sketchup and re installed but i seem to get the same problem am using vray 2.0 and sketchup 2013, seems the problem might have started when i purged materials using vray tools, i have also tried copying the model to a fresh sketchup file but still nothing fruitful, the project is due and am stuck i get this error when i open the file

Error Loading File C:\ProgramData/ASGVIS/VfS/Ruby/R2P.rb
undefined method entityID' for nil:NilClass Error Loading File vfs.rb undefined method entityID' for nil:NilClass

any help will be appreciated, and thanks in advance. i just need my vray back to the way it was thank you
