Uninstall your most recent EP then download and reinstall the digital version from Origin. Instructions here.
I have a Macbook Pro that doesn't have a CD Drive, so I bought one that I can plug into my Mac via USB. I successfully installed the Sims 3 as well as my expansion packs, and it lets me launch the game through the Sims 3 launcher. When I get to the game's title screen (where you choose your household to play) it says there's no disk inserted. What can I do to change this? I've tried just double clicking on the CD when it shows up on my desktop, but it just opens the installer. I only have the problem when I get to the household screen in the game, and I've tried uninstalling everything and reinstalling it, but it still doesn't let me play.
Moved your thread to this stickied one specifically for your issue. Please read the opening post for further help and instructions.
