I would suggest people pick one method of update and not mix and match. If you want to update manually, then don't use Galaxy at all, or just let Galaxy do its thing. The only reason to choose Galaxy is to let it update automatically, or you just do everything yourself. i choose to do everything myself because I didn't want yet another client trying to run all the time. It really gets to be a lot when you think about it. Steam, Origin, U Play, etc. Everyone wants a client on your computer now a days. I'm just glad GOG gives you the choice. But again, i would choose one method or the other and not trying to mix and match, as the previous poster said, they probably do separate things and it doesn't know about what you did, because Galaxy never did the update so it thinks it needs to.
