RuiWell that was bad luck after all. And also, set "Save my map every X seconds" in Preferences, witch prevents map loss and problems like that.

Think about words .. His computer jave been RESTARTED AUTOMATICLY when HE SAVE HIS MAP .
Nobody likes a smartass. Rui probably meant that as a general note concerning map loss.

Ontopic: If the pc crashed while saving the map, it was probably still writing halfway through the file when it got interrupted, thus the file will be incomplete - unrecoverable. - There's no 'fix'.
You should be able to restor at least 25%+ of the data on the map. When it saves a map it writes certain files at a time. It sounds like only 1-2 files have been damaged. With luck you should be able to restore the trigger/object data. Uses WinMPQ to extract files from your map.
