game crashes only on one alt

ok when I play just one alt windows crashes the game. I was playing the alt and was porting to limsa and the game crashed . when I restarted I logged into my main and several other alts and game worked fine then when I tried the alt I had problems with --game crashed. is there some way I can repair the files for the one alt so I can get in?

ok I investigated further and found out game crashes whenever I take a character to La Noscea .
now it crashes when I hit the start button.
here is my current crash log
