I think mine is the same. I'd struggled with sometimes having my saved games available to load sometimes not (would restart computer, verify files etc). Was so frustrated earlier this week as the the most recent saved game I could load was about 12 hrs of play behind where I was so didn't try (I can see the saved game in the file folder but not in the game menu).
The other day updated, loaded and voila - my saved game - didn't have time to play so left it but was hopefully optimistic. Now today, managed to get into the game, was back to old saved game files, restarted and now I can't even start the game, it freezes and won't load.
Have reverified the files through Steam x3 times - NOTHING!!
