Ok, well... It doesn't tell me how to change it. All I know is disabling my AV/Firewall didn't help, nor running it from within the game folder work either.
Right what else did you try? Did you try running the trainer and steam in Admin mode?
new update today (09.04) and trainer may be outdated
need a fix
