Hi from Nifty

Hi fellas i joined your group to get an aimbot for bf heroes.Ive downloaded 1 but am having trouble getting it to work.Im on vista and have never tried a hack before so have no idea what im doing!Someone mentioned a dll injector but i cant seem to find 1 that will work.Even if i do i have no idea how to do this properly.If anyone can help me with some indepth info and maybe some links to get it working will be appreciated.
