[Scharnhorst1943]

If you have DCG installed, any original DGen campaigns WILL NOT WORK. There is a box in the bottom right of the screen when you are selecting what country, rank and campaign you want to play. If it does not say it is a DCG campaign (assuming you have DCG installed) it will not work. Only DCG campaigns work with DCG. All of the stock DGen campaigns do not (Except in a couple of rare casses).
