I notice that the plug-in symbol in the Zaxwerks folder looks different than all the other plug-in symbols I have installed. It looks like a "treble cleff" rather than the "plug" symbol that all the others have.
Also, there's no "Kind" identification eg. say, my Trapcode Shine plug-in is identified as an "After Effects Plug-in" but the Zaxwerks one just has a "0".
Maybe my download is corrupted somehow?
Unfortunately, I've 're-downloaded' the demo again but am getting the same problem.
