That guide (the SuperSuite guide) is slightly out of date and I think was written for older versions of the extensions- you should use the CSS Sculptor Getting Started Guide (available through the Downloads page for that product) for the most up-to-date instructions, and the Getting Started Guides for the individual programmes via their download areas.
In the later versions of CSS Sculptor, rather than there being the option to save presets on the output tab, whenever you make changes either through the 'Customise CSS' or 'Manage Colours' options and then click 'Finish', you will be asked if you want to save the amended design as a preset; you need to click 'OK' (and give it a name) or 'Cancel' to proceed. It is better this way, as it was easy to forget to save the preset when you had to remember to go to the output tab to tick the right boxes. Presets are now managed from the Insert > Webassist > Preset Manager Panel (Choose the Extension from the Dropdown List at the top). If you have saved a preset. it should appear there.
You should refer to the individual Getting Started Guides for each of your programmes for up-to-date instructions for each extension.
Hopefully WebAssist will get round to checking and updating all of the support files in the near future.
Hope this helps
