Is there way to fix save files?

Solution 1:

If you are using Steam to play, the save file should be in "\Steam\userdata\ YourUserID \351970\remote". The save file should end with the extension *.to12sav. Make a copy of this file(s) and save it in a safe place. Uninstall and then reinstall the game and see if this fixes your issue.

Please let me know if you are not playing on Steam and I can try to figure out the location of the save file.
