The SADS application isn't available anymore. It was developed some time ago by Gold Sun, but there hasn't been anything else since. Therefore, if you have it installed, go to the installation folder and look for user guides in PDF or CHM format. Those are user guides and help files that allow users better understand how they work and to troubleshoot any other errors that might appear while you use SADS.
Alternatively, access the following website and and send an email to the email displayed on that page to find out more about SADS, its availability and how it works.
