I just installed the Sims 3 Outdoor Living Stuff pack onto my Late Night expansion game. After installation, the game launcher updated. However, when I try to play Late Night with the stuff pack, I get a message saying "Disc authentication failure. No game disc found! Please insert the Sims 3 game disc before proceeding" and I also get a message about the base game not being compatible with the current expansion pack.
What has happened and why can't I play the game now?
