Problem with Hacks

Guys i really need your help. I tried everythin' but none of this really helped. So the problem is that nothin' appears when i inject the hack.i installed everythin' net framework directX servis pack all of it! but there's another think. when i'm usin' hacks like hydra 4 the one where u don't need injector IT WORKS!so that hack wit loader works! but any other hack where u need injector don't work i mean it injects good but nothin' just happenin'!
Windows XP sp3

oh common man))) i tried a couple injectors and it's the same. injectin' manualy.after login

You can do it before too.
Try it

you inject dll, it doesnt read it right?
and the injector is still open when you login to screen?
