I own Fallout 4 on a disc, and i bought a dlc for it from the store. It says it downloaded and i check the downloads. It says Fallout 4 is not downloaded. It asked me to buy Fallout 4 digitally. I already owned it, so i went to addons as i bought the DLC. It showed my DLC there and i clicked install, but it doesnt install. How do i get it to work with my disc version of fallout 4?
