I have follow the instructions step by step. I have it save in program files/paint.NET/effects, I have opened paint.net several times and even restarted my computer. there is no plugin errors in the settings. I still am unable to get this plugin to work on my paint.net. I got it on the Microsoft store. I have even deleted and downloaded it again just to make sure I did it right. what else can I do or where would this plugin be on paint.net?
