Well, I just dropped 375 points for this game on the request page. As that was all of the points needed to finish the request I hope that we will have an up to date trainer soon.
No problem, mate.
As far as cheats go, I think those are fo the previous versions of the game and that is why they do not work for you. I remember trying them myself and had no luck with them either, so here is hoping that the guys at Cheathappens will give us an up to date version of the trainer soon.
