ah, so there is a limit after all.. That was one of my problems, I also had a problem that i solved using dx9 instead of 11.
I found the trainer rather hard to use. When I give a unit full strength the units i attack bugs, and suddenly all my other units have 263498 strength. And when I turn the code of, it wont go back to normal.
Otherwise great trainer. I think the gold cheat should work by giving 10.000 every time you enable it. instead of 99999999 which is ridiculous
