I updated the Wii but nothing has changed, when i put a disc in it says:
"Unable to read the disc.

Check the Wii Operations Manual for help troubleshooting."

What should i do?
It´s a PAL Wii and all the games i´ve tried are PAL (The Legend of Zelda Twilight Princess, Mario Strikers Charged Football, Super paper mario and Super Smash Bros. Melee)
