There is no information or instruction related to this application. The official website now provides a general page displayed when the domain expired. Also, Google doesn't offer any help at all because all the websites listed don't offer any specific information. You will have to use an alternative since this one is not available anymore.
P.S: You still have the possibility to download it through the Software Informer, but the archive/installation package doesn't offer anything in terms of help or PDF files.
