Keep in mind RumbleFighter was recently plagued with a bunch of GameGuard errors, so it may take awhile for it to start playing good again. In the meantime, don't run RuF with any of the following programs below. The following programs are known to conflict with Rumble Fighter to cause the GameGuard Errors: -Game tracking services (XFire, Raptr, and more) -Other Games (League of Legends, Steam games, and more) -VLC, MPC, any video player -Razer Syapse or any macro assigning software -Joy2key, X-Pad, or any controller mapping software -X-Trap, HackShield, or any other anti-hack software -Emulator software (VMWare)
