Help please :)

I would appreciate if someone could help with my combat arms hacks, I have tried 3 different undetected hacks but for all of them, I inject, load combat arms, go into a game and nothing happens, I even press INSERT for the menu key but nothing still happens, im getting kind of frustrated becuase it has taken me an hour and I haven't made any progress on hacks so if someone could help me I would appreciate it.

Do you get any popups saying dlls are missing before the game starts?
