That means you're trying to run a class. Try starting the other project in the source you downloaded. And next time please use the message forum in the article itself, you'll get better response there.

I think you can record the date user install the software or the date user register the service.
From then, every time user open software or service will compare with the register date.
Hope this give you some addition option
