GOG Galaxy Problems

[[OCN] John Wick ~ Rabbit]

I'm hoping someone could shed some light here. I' am having a GOG problem where it doesn't want to download the updates. Everytime it trys to update i get " Installation failed:Disk access problem". Used the discs to install game and GOG galaxy. I have to install the updates manually. It doesn't just do this for witcher either. It does it for games like planscape torment, etc. Anyone have an idea that uses gog galaxy too?
