Yesterday I downloaded the update for Sins of a Solar Empire, Diplomacy....

Now I can't load a saved game I was playing in for a long time, I get this message if I try to load a game of my own, or an autosave game file.

failed to Read File 'C:\Users\Henk\AppData\Local\Ironclad Games\Sins of a Solar Empire\AutoSave-SinglePlayer\AutoSave-49.save'. desired read bytes = 1, actual read bytes = 0.

But when I look in the right folders, I can see the files there. Is there anything I can change/do in order that I can load my saved games again?
