Sorry mate, third time in two days i've read your post and I still dont understand..
I'm french too, I'd help you but I dont believe we're allowed to speak anything else than english in here and the PM system is pretty weird.
From what I can understand.. and anyone correct me if im wrong,
you seem to be using the legal retail version out of the shelf.
I have never tested it, but from what i've heard trainers will behave differently (stop working) if you are not using the same exact version 'cause there is either added or substracted ASM codes in the exe which causes everything to move (I think?)
With that in mind, I believe using a legal Retail version may causes the trainers built on cracked illegal games to stop working.
Hope im not just spreading rumors around
