ESP help

i need help guys
i tried to use the ESP box for legit mw2. not alteriwnet.
but it never works for me,,none of them
i think the problem is that aero thingy, i'm on vista basic :\
and yeah i ruun on windowed.
i have set admin settings on.
Please help me

1, what hack did u actually use.
2, what do you mean, is it a cracked version or?

If it's cracked it could be that, or maybe the injector ( if u used one ) is not working, or the hack is patched/don't work for you and it may not work for vista..

you can give me more info b answering those 2 questions, make sure the link u give my for the hack is on mpgh.net if it isn't don't bother.
