First off, I'd like to say sorry if anyone views this as a spam thread, and the mods may close this if necessary.
I've noticed a growing number of users either saying that NrN's hacks don't work, or it screwed up their computer.
Thanks to a Mouzie and a few other users, we've determined that his "hack" was a private hack. When injected, a .txt message came up saying something about an invalid GUID, which proves that it was a VIP hack. So no, it will not work for you, it isn't even the full hack anyways.
Secondly, people have been starting to ask about why their Combat Arms is screwing up, or their computer is starting to get infected.
I don't know if it's part of the hacks security, or is it a backdoor implemented in the files. Either way, you need to get rid of it immediately. Delete it. Scan your whole computer with an antivirus, and do a system restore.
But once again, not everyone has been reporting problems. I may be wrong.
