After you register software, then when you click on 'about' and then 'register', do not bring up to enter registration code again. It should read that software is registered (and show the registration key).

Entered the registration code and closed the program. Clicked on about and then register. It did not read that the software was registered. But had me register the program once again. Came back with registration successful. Please restart program. Restarted program and repeated the process over again. Same results. Tried to repeat the process. Same results. What can I do.
