After the upgrade to Windows 10, Ghost 15.0 no longer works. A pop-up showed that I had 30 days to enter the product key. It would not accept the key [Admin Edit: Removed key . It declared the key to be incorrect. So, I uninstalled Ghost and reinstalled it. Same thing happened. Is Ghost simply incompatible with Windows 10, or is there something I can do? I hate to lose Ghost.
