Mistful

Doesn't seem to work for me.
I've installed Scripthook, as well as Scripthookdotnet, and Simple Trainer, but when I press F4, nothing shows up. I put the files in the root game folder, where the launcher is. I've also installed c++ redistribution and .NET files. Currently, I have no idea of what I could have done wrong, and what needs to be done.

Operating System: Windows 10
Game Version: 1.0.1604.1
Scripthook: 1.0.1604.1
SimpleTrainer: 9.8? downloaded: 2019-04-07

Thank you.
