The game automatically creates a backup of the save. It has the same name as the save but with a ~ at the end. If you remove the ~, you can load the save in the game. But consider making a copy of it in case it crashes again.

The game also creates a backup every week (in game time), so if the automatic backup does not work, copy one of the weekly backups to the save game folder to load it in the game.

The saves are here: my documents\pcm14\users\your name\database\solo\name of db\
The weekly backups are in a folder called weeklysave
