S4S tuning error message.

Hiya, been creating cc for a while, always using the same versions of blender and s4s (listed below). Recently I've found I cant access any of the tuning and get an error message importing, changing tuning through the tuning tab or accessing tuning through tools tab. Adding error message below.

Studio version: 3.2.0.3
Blender version: 2.76

The Sims 4 Studio - Version 3.2.0.3

System.AggregateException: One or more errors occurred. (The type initializer for 'S4Studio.TuningEditor.Models.TuningEditorData' threw an exception.)
