i put a new supermario bros for wii in my son's system. it said update was required to 4.2, and now the new game won't read? is this common? i haven't updated his system and never was prompted to before this incident? i called nintendo and they said they've not had issues like this, but gamestop reports 10 or so instances of the same. all his other games still work.
Wii System Update 4.2 now live
