i am using the just updated version (v3.20)
i am just saving it in my personal folder, i'm not sure what you mean.
Wait.... are you saying you're trying to put the script file in the Effects folder? SLS aren't Paint.NET plugins; you have to use ScriptLab to load them. I'm not sure I understand what you're saying. oh im an idiot , i dont know much about these but could you possibly make it save as a pPaint.net compatible file?
