Restart Paint.NET and look in the Effects menu for your new effects
If the effects do not show up, you may need to "unlock" the DLL files. To unlock the dll files, right-click on a DLL and choose "Properties" from the menu. On the "General" tab, look for an "Unlock" button. If there, click it and click the "Apply" button.
