I've played this game day in and day out and this morning when I turned it on, and would attempt to start the game, it would tell me the following: ________________________ Disc Authentication Failure No game disc found! Insert The Sims 3 game disc before proceeding. ________________________ I've tried quitting the game and restarting. Ive tried inserting the game in different times, but I always get the same message. Is there any way to save this? I have thought of removing the game from the computer, and just re-installing it, tho I have no idea how to do that-but not sure it would make a difference. Im not computer savvy unfortunately. Anyone else have had this?
