I had a little problem at first .. the trainer did not recognized the game what I did for it to work is:
Start Trainer
Start Game
Start the mission
Alt+Tab to the desktop
Close the Trainer
Open it again
Activate the stuff and everything worked smooth
These are the steps i used for it to work but i'm pretty sure it would work if you just start the trainer after you get in the mission (after you load or start a new game)
I used the 1.0006 ver.
Do you think it would work the same for the 1.0007 version?
