Although the LS version is mentioned on the official website in one of the change logs, no version is available for downloading or troubleshooting. The same goes for activation. I've used Google custom filters to find our information about activation, but there is nothing.
I recommend contacting the developers to find out exactly if the software is even available anymore. You can do that using the following link: http://www.busy.in/index.php?p=contactus
