Looks like someone was having difficulty with previous releases.
I just had to edit two lines in 'cfg_default.ini' and I have not had any problems since.
Change 'softfog=0' to 'softfog=1' and change 'full_screen=1' to 'full_screen=0'
That's it. Of course that means the game doesn't run in full screen mode so I only nominated it for a silver rating.
