okay guys this hack isnt patched, but it kinda bugs sometimes
try it like this, it might work (it worked for me):
Im on VISTA:
1.- Disable Your Antivirus
2.- Run PerX and Crossfire in Xp Compatibility
3.- DONT run PerX as Admin
4.- If you are using gamebooster dont run it
5.- Enable hacks after you are ingame, do not press hotkeys in the lobby or before.
6.- Disable hack when game is about to end (helps avoid dc)
7.- I suggest you to avoid using screen mode. (game crashes kinda easier)
Hope I Helped guys
Try More than once guys my first two attempts failed.
