Why are you posting here, it doesnt seem to be a trainer problem, unless your using the trainer when trying to play online, which is not permitted. You are not allowed to cheat in online games, so generally the trainers on this site dont work in anything but single player
Well posting only Trainer related questions is not a rule on Title Specific Boards. You can post any relative problems here.
As per the problem, I doubt that it is because of the network connection. Maybe you need to call your ISP.
