un-install the game..delete all files related to the game. and then try re-installing. see if that helps. secondly..if u can..use ur copy of the game and install it on someone else's system..if the problem persists..then ur copy's faulty.
Thank you my fellow gamer for your quick reply. I deleted the game and disabled Nortons while I reinstall and I will see what happens after that. You are so right about education and experience but at 59 its hard to see the fine print
