Need Help Installing AO


I am trying to install the trial version and am having no luck and need further clarification.

I have followed the instructions on the main page but they are vague,

I am using Sketchup 8.0.16846 and am getting this error when starting SketchUp
Error Loading File AmbientOcclusionEx.rb
undefined method `[]’ for #<LanguageHandler:0xf12e10c @strings={}>

Can someone help me.

Thank you

AmbientOcclusion requires SketchUp version 2014 and above.
