Can't load saved games

After changing the instalation folder through the steam app, i couldn’t load my game anymore. So, i tried reinstalling my mods, reinstalling my game, moving the folder back to its original place and still i can’t.
I get the following error message

I am getting the exact same error. I installed the program on my desktop, played through most of the first Act, and then loaded the game onto my laptop. Now the laptop will not load any of my saved games from the cloud but I can create a new game and save that.

How do I restore my saved games?
