My Wii is a few years old now. I didn't use it for about 6 months. When I tried to play it with a Just Dance 4 disc, and then any other disc I have tried, it comes up on the screen with the following message: "An error has occurred. Press the Eject Button and remove the disc, then turn the Wii off and refer to the Wii Opeartions Manual for help troubleshooting." I bought the Nintendo Wii Lens Cleaning Kit, but to no avail--the error meassge still comes up. Any suggestions?
