I have used vray for sketchup 2014 before and then it has bugsplat. I tried to reinstall sketchup and vray. When I open it there is a load error that said:
Error Loading File vfs.rb
Error: #<LoadError: 126: The specified module could not be found. - C:/ProgramData/ASGVIS/RubyToPython.so>
C:/Program Files (x86)/SketchUp/SketchUp 2014/Tools/RubyStdLib/rubygems/core_ext/kernel_require.rb:45:in `require'

I had the same error, the same message was showing when opening the file and I wasn’t able to render with vray (all of this only in one drowing). It ended up being because i rotated and changed the size of a rectangular light by moving its different corners, once I deleted the lights everything came back to normality. Hope it helps.
