I purchased Pride of Nations on Steam 3-4 years ago and I am now trying to re-install it (along with the 4xDLC) on a new hard drive. The install process seems to work perfectly OK and I have an icon on my desktop and I can access the manual. But when I try to launch the game it tells me the game is "Running" for a few seconds and then it stops.
I looked on the Steam forum for help and it indicated it might be Firewall problem with Norton Internet Security that I have installed (although I do also have Revolution Under Siege from Steam and that launches OK each time). So I checked the Firewall Program Control and all the Steam applications (Bootstrapper, Service, Webhelper, Error Reporter) are "allowed". So is Revolution Under Siege (as are the other games that I have) but Pride of Nations does not appear on that list at all. The Steam website then refers people to the game publishers website for more help.
Do you have any suggestions as to what else I might try? Thank you.
