Windows 8.1 won't allow to buy product key online.

I have been trying to license this Windows 8.1 Pro machine, however when I try to purchase the license it gives me a weird message "Sorry, you can't buy keys online in this country or region, but you can buy Windows from a retailer near you.", how come not I'm in the USA and I have bought many others before, please help if anyone here can, I really don't want to format this machine.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Contact Microsoft Store Support. I am not sure if Microsoft is selling Windows 8 any more.

Not 100% sure, but have decided to buy the retail version.

@jdff - Thanks for the update. When done, you might also consider Windows 10 as that will upgrade free once you have Windows 8.1 running.
