I checked the Battleye page and nothing has worked so far. Though recently my computer has been giving me notifications about not having genuine windows, even though I've had it for years with no problems.

I have not ran an Antivirus Check. I'm checking the Battleye FAQ page and will let you know if anything works.

Lex. I just tried that, and when I go to Start Arma3Battleye, it says "Failed to read initialization file."

I do not use ZoneAlarm. And the files stop the game from launching.
