What happend?

On COD MWR today it says wii error take out disc blah blah. I took it out, put it in, worked fine. what the hell happened? Was it because i played for too long? Also is it ok to leave the wii disc in the wii overtime after use?

Um...thats fine, as long as it doesn't continue to give you an error.

It might just be because there was a smudge on your disc or something.

Errors happen every once in a while.
