LOOK YES IM YELLING THE TRAINER WORKS FOR ALL THAT CANT GET IT TO WORK ITS NOT ROCKET SCIENCE, it's easy really i have both the steam and CD DVD Rom versions of the game both updated to 1.05 ok it works try it again until you figure it out its easy really it is when i read these kind of comments i see it makes me and im usually not like that so take my advice it works!!!
Instead of flaming, could you post how you got the Steam versions of these trainers to work.
For most, only the "Numpad 1: GALACTIC CREDIT RESERVE" appears to work for the 1.05 Steam Gold version. I tested this in skirmish and although the trainer indicates the other two options (max units, instant build) are activated, it certainly wasn't true in-game.
If this and the FOC 1.1 (Steam Gold) trainers work for you, please post here what steps you took to get the results desired.
