As i go into the game and click single player and go to play Battle for Europe. It comes up saying that it recommends that i play the campaigns first, so as i go to it sends me back to the first menu to create my Player name again. Bizarre so i created it again and went to the campaign.
Don't bother with that.
If you chose player name, historical profile, nation, and game level which you would like to play, accept this data, then back to menu and start Battle for Europe Campaign.
Then simply click on Battle for Europe button placed under window with that funny recommendation. Wait few seconds and game should allow you play Battle for Europe Campaign. You wll see help F1 window with information about the game, click OK, then you will find window with Global Europe Map.
This is the beginning of this campaign.
You don't need play any other campaign before it.
Hope it hepls.
