I don't wish to take this off topic, but just in case WadeSandoval isn't aware:
You can recover your save from a backup that is in your save folder.
You may wish to make a copy first, then look in your save folder: You will see a two files, and then two identically named files that have ".bak" at the end.
The ones that have ".bak" are the previous save you had made before the most recent one (which is failing to load).
If you delete the two without the .bak, (again, make a copy first elsewhere if you may want them again) and then edit the name of the remaining files to remove the ".bak", then that will allow you to load that previous save in the game.
It's possible that save may also not work- but it might still be good. Doesn't hurt to try!
