If you want to use an NOF system icon for any of your video plugins, you will need that icon in 2 places.

1. In Windows 7, go to the NOF System Folder in the Program Folders.
2. COPY, do not move, any needed icons to the Website Folder > Preview > Autogen Folder.

The first step will prevent a crashed display in Design.
The second will Publish from the Preview AutoGen folder, not the system folder.

Gawd ... I'll be free of this soon, ...
