I got BAA a few days ago. When I try to connect to live, it says it has an update. It downloads the update, but when the installer is just about to finish, it gives the error message "Batman Arkham Asylum has not been installed or could not be found. This update installer will not quit."
I've already beat the game, so it's been on my comp long enough. I certainly didn't move anything. Is this some issue with me running Vista 64 bit?
I was able to open the Games For Windows - Live and download the "Insane Night Map Pack", and that worked fine.
