I have been really upset with WPP since I have been unable to play MP. But I believe I have fix my problem. I don't have a router at home, but I believe the problem is with my internet provider. They are using a router and/or are blocking the game's communication (port 1941). There are 2 steps to fix the problem as follows....
1) Download the Hamachi program. It makes a gaming session by creating a virtual LAN (called Virtual Private Network). Create special player network for WPP game and make a Players list.
My WPP network is "WPPgame", password is 'pearl'

2) Go to your KE Studio/WPP folder on your computer. (NOTE to be safe! - MAKE A BACKUP COPY of your original UserSettings file). Edit the last two lines in your UserSettings file by replacing both "0.0.0.0" with your Hamachi IP address. Save the file. Make sure your opponent replaces his UserSetting file with his own Hamachi IP address. Start up the WPP game, go network play, then one player host and the other player enters the host Hamachi IP address. BINGO - the WAR is now on!!!!!!
FYI - I have not played I full game yet. But the first few turns did work. So I'm happy. Thank goodness!
PS - I don't know how secure Hamachi is. I have known about Hamachi but never really had a reason to use it. Til now!
