So I've found that in windows 7 x64 you must run trainer as admin and press F1 at the "Press Start" screen to activate the trainer. everything works fine, however the unlock all roads doesn't always work how i want. sometimes it turns them all blue but you don't get the discovery credit, some times you do get the credit, and sometimes it just plain doesn't do anything. I've also had it not get all of the roads discovered. so its whatever, also noticed the freeze ai sometimes freezes your car also, found that crashing and activating it as you crash it fixes it, and also hardcore mode fixes that issue. these are what i've discovered with the first release. everything seems fine on latest release
With the latest Trainer Release QA v086 the same Problems occur like in the Version before, using the Freeze AI Option works in Race but if you go back to Map the Game is hung and a few seconds later it crashes, i have not tested the other options so far.
