My Sims 3 game used to work fine, then suddenly it stopped working. Every time I go on the sims3launcher it comes up with 'disc authentication failure' and tells me to put the game in the disc drive even though it is already in. Can ANYONE help me. I have looked on the Sims 3 forums, you tube, yahoo!, wikipedia and loads more. Over all I think I have spent 5 hours or more looking on sites for WHAT I CAN DO!! So please help me if you have any idea I may not have tried..... Thanks xox

1. What is your operating system ?
2. What is the exact message ?
3. Do you have the disk of the latest EP you own ? What do you own except the base game ?
4. Are you using custom contents and/or mods ?
5. Have you checked the disc if there are scratches on it ?

I am having the same problem. My computer is a macbook, I own the sims 3 base game and late night EP in their original cds, I also have used custom content in my game

For Macs, this seems to be one of the ongoing issues. Some people have reported getting it because of custom download or even Store.
Try moving the folder DCCache in the user files (don't know where they are on a mac) to the desktop and start the game to see if it works. If it doesn't, put the folder back and report back. If it does you need to find out what content is causeing the conflict.
Please accept a solution if your issue is solved. XP is also appreciated.
