It's strange, all the trainers and unlockers for v1.2 work ok. But anything made for 1.3 doesn't open. I am 100% positive that I have 1.3, don't really know whats wrong. I did manage to find a v1.2 unlocker that had just what I wanted, so It's not really a big deal, I just don't get it... doesn't seem like anyone else is having the same problem as me. I think I might stay away from trainers now, all they manage to do is crash my game... and thats no fun.
I managed to get the "Cop Corvette" in my career, but the only problem is, without the unlocker activated, it doesn't show up, but when I have it activated, I go to my career, and click "pick a car" and my game crashes... EVERYTIME!! so now there will always be an empty space in my garage that I can't fill
