how do I get trainer to work as I every time I try game crashes
You might want to look at the other posts to see why it's not working, Ubisoft is throwing out patches to break the game and hotfixes to break the game even more. Plus you probably would've wanted to make that post in the appropiate topic and not one that has to do with key binding... Please learn from this lol.
If you don't have an issue with key binding, good for you, move on? So negative.
I'm having the same issue, was working before the latest game update and FAR CRY 4 TRAINER 1.6.0, now it crashes when I enable the trainer.
For the record:
8.1 64 bit
AMD Quad core 3.9Ghz
NVidia GTX-970
8GB ram
3TB HD
The development team may look at the game again after the holidays.
