I tried to log in to my machine and when i did so it said my product key was invalid. This is complete BS so i tried the "retype product key" option. Typed the key from the bottom of my machine and it said the same thing. I have emailed Microsoft but i have to wait for 24 hours for a reply. Again, BS. Has anyone else had this problem. This was completely out of the blue. I haven't done anything out of the ordinary with my computer.
