Fall Further isn't being developed any more, the last patch came out more than 2 years ago. You might want to check out Rise from Erebus (
http://forums.civfanatics.com/forumdisplay.php?f=360) instead -- that started out as a Fall Further modmod, but has been and continues to be actively developed.
It's remotely possible that someone will look at your save and try to fix what's causing the crach so you can continue playing your particular game, but I wouldn't count on it, sorry.
