After entering the license key, a dialog states that I have successfully registered Auslogics BitReplica, and that I will need to restart for the changes to take effect. After restart, the program still shows that the program is not registered. I tried again a couple more times with the same result. I had closed the program using the X button in the upper right of the program. Next, I tried existing from the File menu, and when I restarted, this time the program was registered. Since closing a program using the upper right X should work the same way, I see this as a design flaw. Once the dialog shows that the program has been registered, then regardless of how the program is closed, it should remain registered.
