I hope you didn't follow Isak's advice yet, it's far simpler than that.(Sorry Sir Isak)
Quite allright, Sir Civalaholic, but I feel I must point out that it's not (necessarily) that simple. Since version 0.31 there has been a file named
civ3mod.bic in the main Civilization III directory by default (if you install the patch correctly, that is.) That file
is the DyP-mod Bic.
I've experienced this bug myself once, with one but also with
two bic files in the right directory (one named "civ3mod.bic", the other "DyP v.0.2.bic") and nothing happened when I pressed the New Game button. It was as if the button just stopped responding.
Replacing the bic had no effect, only thing that would do the trick was the procedure mentioned above.
I remember giving the same advice that Civalaholic passes on, and yes, if there is
no bic file, the same thing happens - but the problem now is: If there's no bic in the Civilization III directory, you've installed the DyP mod incorrectly, and
all files will be in the wrong places.........
[Edit: Just realized - If you have no bic in the Civ3 directory, you've installed
Civ3 incorrectly - not just DyP

]
Thats why
U.R.P.I. is the only way to go:
-
Uninstall Civ3
-
Reinstall Civ3
-
Patch to version 1.21f
-
Install Double Your Pleasure
