i have tried the instructions given for the crash, i rolled back my display driver to 340.50 nvidia the ones supposed to be optimized for this game, i removed my security programs only thing running is bitdefender security suite with game profile enabled. i have run a complete scan of the system, i reinstalled the game. i make sure all background apps are off cause i found if malwarebytes started while i was playing FFXIV.exe would just close no error no message so i removed it. only thin on when i play is cloud sync, game, winamp and bitdefender in game mode.
