Contact Microsoft Customer support and give them the product key and CD part number

It will be in the inner circle on the Silver side of the Disk . It will be some thing like


They will provide with a new product key

Some times the activation systems cause trouble like this they will simply issue a new product key free of cost if you have the correct part number
