Splines that works in Windows Store apps and Windows Phone Store Apps

Hi,
I recently bought the SplineTool by Dmitrii (http://u3d.as/content/dmitrii-prihodko/spline-editor/2Bv) and it works fine inside Unity and when I export as EXE file, but when I export to Windows Store Apps or Windows Phone App I get exceptions (out of bounds or "A script behaviour has a different serializastion layout when loading")

Does anyone know about a good spline tool that works for Windows Store and Windows Phone Store? I want to make stuff follow paths

 

Curvy works on all platforms
