Suddenly my legitimate Win7 Pro popped up a message saying it was not genuine, and I needed to reactivate.
I reentered my product key, and it said that it was no good, and directed me to go online to purchase a new product key!
I was getting ready to raise hell with someone, when I retried the product activation wizard after rebooting, and it finally re-activated my copy.
Has anyone else experienced this? What could be the cause?
