Error on loading.

[ContinuumXIX]

So all through yesterday I've been having this application error come up every time I try to load the game.
It keeps saying The instuction at 0x00f78975 referenced memory at 0x00000044. The memory could not be read, then shuts down the game.
I've already restarted my computer and reinstalled the game 5+ times now, and the same error still comes up.
Does anyone have any idea on what I should do? :l

EDIT: I managed to fix it now. Had to run a file check... I still don't know what caused it though.
