I have bought a pc from a dealer in welkom. He gave me a cd with a product key. All went well. I got a problem with my pc and had to format my harddrive. I re installed Windows 7 from the excact same cd with same product key and now I’m receiving messages that its not a genuine copy of windows. How can I correct the problem without buying a new product key or licence? Thank you. Marika
