I downloaded shaders from alias wavefront. I put it in my "D:\Program Files\AliasWavefront\ShaderLibrary\shaders" folder. However, when I use hypershade, in stead of displaying icons as a preview icons, all the shaders that I downloaded and installed appear as small maya logos.
I can use those shaders, but it is inconvenient for me to use because the icons are not displayed as previews. I think that is something to do with the ".mayaSwatches". I appreciate if someone can help me out with this.

Ohyeah:
