What you have there is V3 of the old DOS game and that is
not compatible with the windows based winSPMBT.
I'm not quite sure where you see it called the "enhanced version" however and it would not have been purchased because we didn't offer a CD version of the DOS games and on top of that, I don't recall that photo in the screen shot that appears while the installer is running. Where did you get this ?
So the reason your game will not run is because you are trying to patch an old DOS version of the game from 8 or 9 years ago with the new Windows version patches of the game. That is a first for us I must admit.
Finally, even though that screen shot is a full sized BMP I cannot read what it says at the top left corner. Could you please tell me what it says exactly.
