I suspect that you’ve copied the attributes.rb file over from an earlier version of SketchUp and it’s not compatible.
Posting the first line of an error message is not very helpful…
I suspect the full error is because the file you have been trying to get loaded is either not encoded as UTF-8 and/or has syntax errors that break the Ruby that is now used in SketchUp [since v2014].
To stop the errors simply remove the file C:/Users/jema/AppData/Roaming/SketchUp/SketchUp 2016/SketchUp/Plugins/attributes.rb or rename it with a final ! so it doesn’t load.
You could also use the SketchUcation Plugins Manager to do the same thing without having to try and find, then open your [hidden-by-default] C:/Users/jema/AppData/Roaming/SketchUp/SketchUp 2016/SketchUp/Plugins folder…
