NutScript was a very old, unstable framework. I believe the developer(or one of them at least) got conscripted in the army and abandoned the project. The good side is that it got reworked into Helix which is a much better alternative(and it's based off NutScript!). You can check it out online, it's free and they got their own website along with a helpful community and a *currently small* variety of plugins you can use.
