Heres a fix for the problem we found
drigate crash look at page 21.
If you dont feel ready for a little cut and paste hack then you can download the two PediaIcon files on page 22.
Here's the fix itself
Needless to say, back up these files before trying this
I'm assuming you've done a standard install for file locations
Look in C:\Program Files\Infogrames Interactive\Civilization III\CIV3PTW\Text
Yes wordpad is fine as a text editor. Find the following text
#ICON_PRTO_Frigate
art\civilopedia\icons\units\31frigatelarge.pcx
art\civilopedia\icons\units\31frigatesmall.pcx
and change to
#ICON_PRTO_Drigate
art\civilopedia\icons\units\31frigatelarge.pcx
art\civilopedia\icons\units\31frigatesmall.pcx
#ICON_PRTO_Frigate
art\civilopedia\icons\units\31frigatelarge.pcx
art\civilopedia\icons\units\31frigatesmall.pcx
Further down find
#ANIMNAME_PRTO_Frigate
Frigate
Change to
#ANIMNAME_PRTO_Drigate
Frigate
#ANIMNAME_PRTO_Frigate
Frigate
The PediaIcons may need to be changed in this file (I didnt test if it was required but it doesnt crash if you do make the change)

#ICON_PRTO_Frigate

Change to

#ICON_PRTO_Frigate

This allows both drigates and frigates to be built without crashes
