I have checked the official website, but the domain expired, therefore it's impossible to obtain a proper user guide. Based on the searches available though Google, I have found a page on the old domain where all the information was provided about the software, but since it's discontinued, its impossible to obtain it now.
If you have the software, check the installation folder. In some cases, developers place user guides or manuals in that location. You can find the information in TXT, CHM or PDF formats.
