My Xbox 360 just started freezing today and I get the three red lights. Also the disc tray is stuck shut needs to be pryed open evertime I go to play. I got the warrenty when I bought it and had to sign my name on some list. I lost my recipt though, can I still return it? I bought it at an EB games store in Witchita Kansas, so could I return it to another EB games or Gamestop store with out the recipt?
