I had to upgrade my laptop because Win 7 got so many errors on it and I couldn't fix it. So to make a long story short I upgraded to Win 8 Pro x64.

Since I don't have a legit key activation fails, but I want to buy it and when I click on the buy it link it says I have to go to a retailer.

My question is how can I buy a license? If I wait until late Oct. will it work then? How long can I wait with not activating it? I don't want to ge locked out.

It is Win 8 Pro Build 9200, don't think it is MSDN.
