Why can't I load my save?

Just started up the game for the new update (1.1) and the option to continue is gone, the option to load is grayed out, and starting a new game shows none of the save slots are used.

My save files are still in the appdata directory (and I have backups anyway), and my settings didn't get changed to defaults or anything.

Is there any way to fix this shit so I don't have to start all the fuck over again? I was hella near the end of the game...
