Hi All, Had a message on the SP2 this morning to Activate windows. Clicked through the process and it came back with... "Activation Error 0x004C003" "The activation server has determined the specified Key has been Blocked" It has been fine for the past four days since I bought it. I called msoft and they said use the Key on the sticker on the box. It didn't come in the original packaging, so no sticker and thus, no Key. Msoft's reply, buy another copy of windows. Vendor not answering emails or phone -- but it is Sunday! What can I do? Well, besides wait to contact the vendor on Monday.
