After Firaxis has released the 1.21f patch for PTW there have been troubles with PBEM games.
This is due to the fact that the new patch is for the US version ONLY!!!!!
Sadly, it seems the patched US-version savegames are NOT compatible with non-US, NON-patched versions!!!!
if oyu play a turn on a patched game, save and send it on, the next player will NOT be able to load it properly UNLESS he/she is patched, too!
I claim no credit for knowing the answer to this, but I dont know how to do a link so I have copied this from another post (actually from hhj's many pbem games). Also a mod might wish to put this as a sticky as, temporarily at least, it will be useful to many people.

If you have already installed the new patch and you want to continue to play PBEM games with people who have not or can not get it you need to create two distinct installations of Civ3
TW on your PC. This is how you do it:
Copy the entire CIV3PTW folder to some other directory (perhaps C:\), and rename the copy (perhaps as "CIV3PTW v1.21f").
Uninstall Civ3
TW and restart your computer.
Reinstall Civ3
TW.
Download the v1.14f patch from here.
Install the v1.14f patch.
This way when you launch Civ3
TW normally, it will pull up as v1.14f. When you want to play v1.21f, browse to the copied directory you made and launch "Civilization3X.exe" (the executable). You can also create a shortcut to this file on your desktop; just be sure to label it as "v1.21f".
Note that even when using two distinct installations, your default Saves folder will always be in your Civilization III\CIV3PTW folder, and **NOT** the copied folder you made!
This has been tested; a save game sent to me (in UK) worked fine.
