Wierd?

For some reason whenever I try to use hacks it never seems to work. Ive tried every perx combination with dll's and it always says injected and then when i go ingame and press the hotkeys to use them, nothing comes up and the game doesnt crash either. anyone know why this could be?

yup its on xp sp2 right now

Change it to Windows 95 or 2000 like the guy above just said
