I am having to send my 360 in for repairs for what they say is an optical error (scratched my NHL 07 up 2 disks, 1 cracked).
Games wouldn't load up and I would get the white screen saying "put this game in a 360 console."
Customer service guy told me to plug my 360 into the wall and not in surge protector or power bar. No luck, then he told me to TURN MY AUTO DOWNLOADS FOR LIVE ARCADE ON.
Games suddenly started working then. My horribly scratched NHL, 3 ring scratched Guitar hero 3 and my Mirrorlike Tiger 07 would start up immeditely while PGR3, TOMB RAIDER LEGEND (both mirrorlike will not). OXM discs will not start up either.
Funny thing is none of these problems occured before the update that gave us the option of autodownloading all arcade trials and free games. HMMMMMMMMMMM! why did the guy know to tell me to do that?
So even tho my hockey works(my main game) I am sending my 360 in. 1 month before the new release!!!!! I am going to have to rent a 360 for 1 week so I can play my pre-ordered hockey. Better waiting a week later than sending it in 1 month after release lol.
So try setting your 360 like this,
Auto login (your gamertag)
Set arcade downloads to Auto on
after doing this power down your 360 and try loading your game up and if it doesn't work try again.
hope it helps
And the beat goes on and on and on and on.
