seemt that achievements are registered in game only and do not unlock in steam.

I got to the end of the first chapter, and the game said to save it. I did that, but now when I try to load it just starts again at "make sure sure to save your game", and takes me to the save screen again. How do I continue into the next chapter?

I have tried uninstalling and reinstalling it. It says 'missing game executable-' and then the program files. Any idea how I can fix this? Anyone else having this issue?

Add some, please! ^-^
