Hi, Well a couple of minutes ago I was playing wii without any problems, a backup of no more heroes 1, then suddenly, wii start to make huge noises and gave me an error of can't read the disc. I turn off my wii and when I turn it on it won't read any of the backups, well I tried a original game, but it also don't read it. Then I tried to update cios to rev17 but still don't read, clean with lens cleaner and also nothing. What can be? Shoul I update to 4.2 Official of Nintendo? Help please, Thanks for any help.
