Just re-downloaded Napoleon Total War today from Steam. Trainer doesn't work. Ran in admin mode and everything. Even tried Trainer #5 in place of #6, but to no avail.
Bummer
Version in game says 1.3.0 Build 1707.284994
Not sure if that helps, but there it is.

I don't have any problems with the one I have, the latest one that is. Sometimes if you rush the trainer to load it will stop working. What I mean by rush is that you try to start the game or do anything else right after you click on the trainer. Other than that, I don't know what the problem could be.
