There have been some theorys taht using eu hackshield on naca will allow u to used patched hax. My theory is:
1)Hackshield sends a message to hackshield hq or w/e, and it will update it to us version.
2)Eu hackshield will send a message to the EU hackshield hq or w/e, which may screw up ur game.
Just my theory though, feel free to share ur theorys/opinions
