Well unfortunately, none of this has worked. I did finally get a reply from EA/westwood their responce was, (1. from one tech person) "XP pro is not supported, (2. from a second tech) Nortons prevents the game from running the only way to get the game to work would be by uninstalling Nortons and dune, then reinstalling the game and not installing nortons will allow the game to work". at this piont I am un willing to unistall Nortons... not untill I get my new system up and running....
