I bought the package and dragged them to where the other shaders are in Carrara 5, but when I open the program and bring up the shader wizard, none of the new shaders are there.  I though there would be a folder called art of shaders, but I'm getting nothing but the ones that come preinstalled with Carrara.  I did not get a read me file when I unzipped it, so could somebody help me figure out how to install these, cause I pid for them and would like to use them.

Thanks.
