Hello, I wanted to play some New Vegas, however vortex cannot find the app of the game. I have been to manual setting and in the excact file, as the app is to be found in files, Vortex does not show me possibility of choosing it, simply not seeing it in files. Any suggestions? I am a technological ape, it might by some stupidity, but not even long hours in I did not manage to wrap my heads around it. Many thanks for your time
