One night i was playing animal crossing about 12:30 then i turned it off took the disc out and went to bed. the next morning i went to play animal crosing and a message saying "An Error has occured. Turn the power off and check the NINTENDO GAMECUBE instruction booklet for further instructions" I did and it said my cube had a problem internally!! So i put a different game in and it worked fine, i put AC back in ande the message returned. Is my CUBE broke?
