Michael, when you didn't specifically click on the "reply" button from MY message, I wouldn't be notified by the system that you have posted new comments. I was scrolling through all of the threads I was involved in and saw your comments. Sorry for the delay.
The command is actually DLV at the end. It is an L, not an i.
Anyway, the purchase detail actually helps anyway, so no need to rerun the command.
Try this:
You can go to Settings > System > Activation > Change product key
Disconnect internet, and disable any third party antivirus, key in the generic key instead: VK7JG-NPHTM-C97JM-9MPGT-3V66T
That should get you to Pro. Once restarted, you can connect back to the internet, sign into your Microsoft account. See if it is activated.
