Aldudeau:

I've extracted the contents of the zip file to the CPS 3.0 Documentation file to C:\Documents and Settings\MyName\MyDocuments\maya\5.0 folder.

the files and directories in there now are:

prefs
presets
scripts
cpsControlReference
cpsReference
cpsToolboxReference
examples
faq
images
installation
overview
tutorials
Maya.env
index.htm

(Bolded are the directories that extracted from .zip file)

The instructions say that there are supposed to be .xpm and .mel files, but I don't have any.

I go to run cpsSetup in the command line and get:

cpsSetup;
// Error: Cannot find procedure "cpsSetup". //
