Import Curvy from json Issue

[mlndb10wN]

Hello,

   I am importing a json created by json Utility with a SerializedCurvySpline. 

Code:

  SerializedCurvySpline newSpline = new SerializedCurvySpline(JsonUtility.FromJson<CurvySpline>(File.ReadAllText(pathPath)),CurvySerializationSpace.Global);
           CurvySpline cs = path.AddComponent<CurvySpline>();
           cs = new CurvySpline(newSpline);

I have tried this several ways and it complains about two things.

1. Assets/Plugins/Curvy/Base/CurvyUISpline.cs(17,18): error CS1729: The type `FluffyUnderware.Curvy.CurvySpline' does not contain a constructor that takes `0' arguments
   
2. Says that the constructor of CurvySpline doesn't take one argument. 
   

Is this something to do with the partial classes and the inheritance in UICurvySpline? How do I make a new CurvySpline from a json?
