Crysis 3 Cheats
Other people have gotten the trainer to work thus it is not a global issue or an issue with the trainer. Since you have neglected to post any detailed troubleshooting information that can help us reproduce the problem on our end, we cannot assist you in anyway.
Anyway here's something else, you can bind some of the previous games console cheats to the C:\Users\USERNAME\Saved Games\Crysis 3\game.cfg and GFE.cfg
These two files normally re-save when the game starts so you lose any added commands thus you need to set them as write protected / read-only.
Ideally you'd want the commands in the difficulty cvar file as that loads in a better position and thus ensures the commands work properly but since mods are only partially implemented (You can load them but they don't really do anything.) which means custom files won't work then this will have to do.
For example by adding g_infiniteAmmo = 1 to those two files you should notice the guns have 999 ammo reserve, you still need to reload though, can switch to special ammo and reload to get 999 of that too.
(The rest that I've tried only worked sporadically but this one seems to stick through the entire game for some reason.)
Combined with the trainer functionality you can now have unlimited ammo and the no-reload option or what other functions are desired, pretty useful.
(Having some way to restore the original console commands or un-restricting it or whatever is needed would be better but that won't happen outside of the sandbox editor should one be released.)
Since all we have are "fake ass trainers" then you won't be needing your account any more.
Anyways.... I will give a heads up... when later on you disable the Air Defences on a tower, make sure you turn off options before you destroy the generator... the bridge you have to get across to get to a lift actually.... lifts up making it impossible to get over when an option is on... haven't pinpointed which one but I think its the energy one.

all the trainer does at F1 is inject trainer code into the game space. there is no good reason for the game to crash since no game code has been modified. maybe something on your end is detecting injections and closing programs. i have no good answer for your problem, since the trainer isn't really 'doing much' when you activate..
also, make sure you are downloading an authentic cheathappens trainer FROM THIS SITE. otherwise, it might not be functioning properly..
