What happens why you load the game? Do you get sent right to the start, where you are asked to name a tribe?

If so, your savegame file is probably corrupt. Close the game down and look in the folder where the isola1.ldw file is found. There should also be a file named isola21.ldw. Rename isola1.ldw to something else (such as isola1.ldw.bak) and then rename isola21.ldw to isola1.ldw. Start the game and you should have your village back. Since it is an earlier backup you may have lost some things that happened a short while before the game crashed.
