You have to use Cheat Engine until PWizard gets back from his Vacation! If you have to, look up a Cheat Engine Tutorial, It's good to know how to use this, because then you don't need to rely on trainers as much, there are still things that PWizard's trainers do that are more complex than Cheat Engine could possibly do tho.
Same with me. None of the Barraks options work (Money, Soilder editing) but the mission ones work 100%. Wasn't sure if it was because of the tutorial or not.
PW Enjoy your vacation!
