I have the following problem every time time I try to reload the game.
I re-install the program up new version.

First time i play first turn it works. Switch off.
But when I try to reload the program I get the following error.

Exception EAccessViolation dans le module cw2.exe
dans 0043649D
violation d'access a l'adress 0083649D dans le module cw2.exe lecture de l'adress 00000000.

I have played this game and it happens all the time. I have reloaded the game. Same error.

Thanks
John
