The developers of this application are not in the business anymore. I have searched for their website, but it doesn't appear to be available for accessing. No, it doesn't mean the software has changed its license status to free. If you require a license key, then it will still be shareware. I believe you will have to look for something else, because software and its modules won't have support for future OS and updates.
