My original flash drive failed. The content is readable under Windows but cannot boot. I made new one from old backup. Booted, then Tools -> Registration -> REPLACE KEY. Pop-up appeared I logged, my server was indicated. I closed the pop-up as instructed, pressed the FINISH KEY REPLACEMENT button. But instead of ending the process I got the same pop-up again. This cycle was repeated several times. Then I decided to update OS and went to the pop-up again but this time there was no FINISH KEY REPLACEMENT button.
If someone can help me about what I did wrong and Is there any other way to replace my key?
