Forum:Invalid Disk, please help.

I was just about to play the Sims 3 when the launcher told me there was an update available. So, as I usually do, I downloaded the update and proceeded to play my game.All was working fine until I got to the menu, y'know where I get to choose what family to play on, as soon as that page was up a little window popped up saying "Your disk is not valid, please contact customer support" or along those lines. The only option was to click the little check mark, and then my game shut down. This has never happened to me before and I think it has something to do with the update I installed. If I can't get any help I will uninstall the game and lose all my data. :( Please help
