I bought the game a year ago and my girlfriend and I started different games. She finished her play without any problem, but I couldn't because everytime I tried to start the fifth episode, the screen turns to black and the game didn't start. I tried to rewind the game to start in a previous point, and it didn't work.
After a few months, I started a new game and, oh surprise, the screen turned into black when I started the third episode.
I had an unofficial patch translating all text to spanish, and i don't know if that can be the cause of my issue.
Anyway, here is the file generated by the support tool, as it may be useful for you to help me.
Thanks a lot.
