Ken,
Were you able to open the program properly yet? If not start from ground again. Download the program from the Korg Pa Bonusware page link I mentioned before. Then unzip the file. Inside you'll find many PDF documents which are the manuals in different languages. In the English manual you can read the instructions step by step. After you start the program selecting the Set Up folder a notice will pop up with the Serial Number and Pin 1 of your program. In page Nº 6 of the English manual you will see this link: http://www.emc-musicsoftware.de/viashop/storefront/start.asp? . In that page select the English flag and then "Registration" then fill the form including your Serial number and Pin 1 and later you'll receive a mail with the Pin2 you need to keep the shareware for free with limited functions for unlimited time. If I did it, it shouldn't be that hard .

Thank you Victor for this additional information.

I have given it a try.

Cousin Ken
