The creator of the program has closed. How to get access to the program that was bought from him?

Question

Licenses for software and other works

Hello!

There is a program teaching English.
Bought a long time ago with a license key.

Now the company that developed this course is closed.

Question. How can you break the verification of this license key so that the program works?

I brazenly ask, because instead of sites on the packaging, something incomprehensible in Chinese opens.

The program is called English20 Interactive.

Answer 1

It must be assumed that the program checks the key on the server and does not start without this check? If it is still impossible to contact the author in any way (by soap, search in tyrnet) - then just break off the check.
