It looks like a save file was corrupted by the blue screen. If you pop open the save folder (type %APPDATA% in the start menu if you have hidden folders showing), you can back it up and clear it out to get things working again. Fixing the save file may or may not be possible depending on how corrupted it is.
So sorry but I'm not very familiar with this, but what do I clear in the save file?
It's a little cluttered in the save folder, bunch of old saves that I've since deleted in game but still remain as well as the error logs.
Also, which of the files in the folder is supposed to contain CG and Achievement progress?
