Hey Cliff, just found a bug in the demo. Follow these steps to get to it.
From the main menu:
-> Click “How to Play”
-> Go through the help popups until you reach the one that says:
“Lets look at some statistical data more closely. Click the blue icon with the word GDP on it, over on the right had side of the screen”
-> Click “Options” up in the main toolbar.
-> Click “New Game”
BUG: The previous tooltip is still active and stops you starting a new game!
-> Click “Go back”
-> Click “How to play”
-> Click “Next” on the first tool tip"
BUG: Game crashes to desktop!
This happens every time i try this so I’m sure it will happen with you too. Just thought I’d inform you of this 
I’m running on window vista business edition.
