saves not working

Am I the only one who have problems with saving and loading the game?

I usually save new saves instead of saving over the old one but for some reason my saves aren't working.

At first it was only the last save and my auto save won't work but I could fall back to a older save to load the game. Now none of my saves are loading, it just sits on the loading screen without loading the game.

I have like 14 progressive saves up to 92% of the game completed now the only one that works is the one at 8%. What hell is wrong with this game on steam?????
