I bought Windows Vista at Circuit City for $200.00, I tried to validate it and it says that my copy isn't genuine. That's not true. Now i cant use my computer. And It wan't me to pay more money for something i have already paid for once but says United states is out of scope. I think you people want to just screw us out of as much money as you can. I don't think it's fair i can't afford to but another one. thanks for nothing. I liked Windows xp better. But can't buy it anywhere.
