The Org Plus application appears to be developed by the Broderbund company, however, after using their website to search for Org Plus, I come to conclusion that it is actually discontinued. There is no trace or any other information related to the availability or trial of the software, therefore if you want to obtain a key or additional details, a direct contact with the developer needs to be established.
You can use the following website to obtain the details you need: http://www.broderbund.com/c-4-contact-us.aspx
