Hi, I wanted to see if other people are also experiencing the same issue. I've owned my 360 for about 2 - 2.5 yrs never had any problems. I was able to play MW2 and a few other games on Wed night (18th) after that I didn't really use my 360 until today - I was asked to update my system and since then none of my games nor any of my dvd's movies work. The error I usually get is disk unreadable or open tray - I never had any issues before today. I tried 5 games ( 2 that were brand new). I also tried to clear the cache but nothing seems to work. So as of now I'm sitting with a non functioning 360 should I call mircosoft or wait for them to issue a newer update?
