    I explained how to make it reappear above... You should close the activation window, then go to Control Panel > System and click Activate Windows one time, and the Activation page will appear with Activate button.

    You can try this. Open a command prompt, and type
    slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (Windows 10 generic key -- you can find it on the previous page)
    then type
    slmgr -ato

    That won't work because (I assume) you were using Windows 8.1 Home, and you were eligible to update to Windows 10 Home.
    Changing the product key to the generic key of Windows 10 Pro won't work, as you didn't upgrade from Windows 7/8.1 Pro.
    I kinda felt that won't work as well, so I went the hard way and installed w7 pro, then upgraded to w10 pro, and glad it is activated now.
