Let's have a look at the error log:
C:\$WINDOWS.~BT\Sources\Panther\setuperr.log
You can post in code brackets using the "#" icon in the top-right.
One more thing: I assume, since you upgraded this rig once before, that the installation of W10 was "activated" and so you already have a digital license for this system, therefore the deadline for tomorrow's upgrade does not apply to you, correct? Did you verify the system was activated before you rolled back?
EDIT: You'll need to copy that log to your desktop, in order to open it in notepad.
