Still doesn't work since my video board support until DirectX's 10.1. Probably my architecture is too old for that engineer of Construct 3 as you said.
Thank you for your help, will play when I have a better PC :)
Actually, I have a PC from 2009 w/ a videoboard of the same year, and when I try to play, my game just freezes on a black screen after I finish my character.
I can run Fallout 3 or NV but didn't this one. Do you have some idea about why?
