Cloud save trouble

I am currently away from my main computer, where I played the first four chapters. I decided to use my MacBook to try and see if I could play chapter 5 tomorrow on it instead, and I found that my saves did not transfer over, which sucks, but whatever. However, I did notice that my cloud data saved and now presumably saved over my previous data with (effectively) a brand new copy of the game. Will I still be able to retrieve my previous chapter clear data on my main PC when I get back to it? I haven't uninstalled the game, so it should be fine, right?
