The trainer is active? It looks so... but does it work with the last steam version? Because last active trainer I used (Fallout 3 new vegas) was useless... It works, but after one mission the game crashes and the notepad doesn't say anything about this issue.
I have the same problem. since i added pirates heaven DLC the trainer doesnt work. you hear the trainer activates sound when u press f1, but when ingame and pressing 1, nothing happens. for me pressing 1 many times result in game crash.
