eh ok. so heres what i did when i had the error
i simply eh. deleted every file i had of the game every **** thing. then empty the recycle bin
then redownload through aeria then eh.. that does it.
But if your unlucky like me after the first time it works well. your pc goes all crazy eventually and deletes the update by its **** self.
Then simply delete aeria everything you have on it then re download the whole thing.
Hope i helped
*The pc going crazy was not due to the download of the eh... update.
Updates works perfectly fine.. tell me how it goes.
