Hi! I just bought GTA IV to computer just for Simple Native Trainer and that LCPDFR cop mod (or something like that). I have watched all kind of those tutorials and other stuff related those mods. I have downloaded many kind of those dsound.dll and trainer things.. I have putted those files to that main directory and used all different tutorials but my problem is that when i start my game and press F3, nothing happens. I'm little confused to this problem because i have searched from many places this problem but i haven't seen it.. Please help me! (sorry for my bad english) + Could this problem result from that i haven't done a single mission in this game?
