I have had my wii for over a year, and I have never encountered this problem before. I put a My Sims or any other game in to the Wii and it says the following "An error has occured. Press the Eject Button and remove the disk,then refer to the Wii Operations Manual fo troubleshooting." On a black screen with white letters I really need to know how to fix it. I can do other things fine, but I can't do the most important thing play the game.I really really need help since I threw my Operations Manual, because I thought I did not need it. The games are not scratched or anything. I just keep getting an error screen.... http://www.wii-games.asia/nintendo-wii...
