i used to have that problem, and running in as administrator fixed that, and if you are running as administrator, i also found that it will not activate if both the trainer and game are ran as administrator
This ^. Both run as admin.
my issue with the game is stability with the trainer on, I ONLY really need it for unlimited Ammo and super weapons, because I use TGM from the ~ menu.... This is still an active trainer, so Is there a remote possibility someone here can still fix the Game Freezing issues??? I have a great computer... It runs all Much newer games perfectly, like skyrim,etc.,

You might want to check that out. There is no real fix, apart from editing the exe to handle more than 2gb, and editing the fallout.ini to handle multi-core cpus. the game is a memory hoarder, and will crash even with trainer or mods.
CH's fix is allegedly alt tab back into the game, that hasn't worked for me though. I am able to run the game anywhere from 30 minutes to 1hr 45min. Depends. Also windowed mode helps a lot.
I have win 7 x64 12gb ram and A gtx 560Ti. It should be able to KILL this game, but yet it crashes.
