Okay, so this is quite a common problem I'm assuming.
I was playing FIFA on my Wii earlier, when it suddenly stopped and told me to eject the disc and remove the power supply (something along those lines).
Anyway, I rebooted, started okay, almost got into playing a game, then the same happened.
Ever since this has happened I haven't been able to play because of the same error, none of my games are recognised (all are in good condition)
I have a disc cleaning disc, which I used in the disc drive. This helped a little as the game was then recognised, but soon after I got the error message.
Has anyone else managed to fix this problem themselves? We've only had the Wii about 18 months
