Game not installing

i recently tried reinstalling endless space 2 but when i tried it didn't work because it said that it had a disk write error and i think that the problem is that the game is trying to install pdfs of stroies for dlc i dont have, the hissho and the umbral choir, when i deleted the pdfs it ended up dowloading almost fully but then ending up saying that there was missing files then tried redownloading the pdfs then had another disk write error. i was hoping someone could either provide me with the pdfs so i can just place them in the folder or give me another solution that would be greatly apreciated.
