So I had that bug against the wizard (after hooking up with Keira) who summoned the hounds, and was protected by a shield. Turns out his perma-shield was a bug. Various fixes said to verify the game. So I did that and now GoG Galaxy says my installation is broken.

I would like to know how to fix the game.

Edit- Seem to have it sorted now. Thought it would require redownloading the game. Managed to work around that problem.

And the fix was?

Oh yeah.

I uninstalled the game, and reinstalled it from the laptop I originally downloaded it on. The laptop in question, I was able to leave at a friends place to download a game off Steam using his Internet. It was a time consuming process, and I would have preferred something faster, but, eh.
