I reinstalled a previously working version on of Gallactic Civ after reinstalling windows. I logged onto my account and re-registered the product id so I could download the retail update. I downloaded and installed with no problem. Now when I go to start the game, I get this message:
"The producte appears to be validated but the serial number or machine SID do not match"
My serial number is correct, right off the jewel case. What am I missing?
