Any way to fix game files without completely reinstalling?

[Mhaeric]

So, I finally decided to do the Ivalice raids, but every cut scene in the questline seems to have some sort of error and crashes my game. I can just skip the cut scenes, but that kind of defeats the purpose of having a questline in my opinion. I remember this happening when I was leveling during Stormblood in that there was a cut scene where the game would just crash every time I tried to go through it and I reinstalled the game and it fixed it, but I would rather not have to do that if I can avoid it. I have the non-steam version of the game. Any help would be appreciated.

FFXIV doesn't have a repair files option, unfortunately.
