Are you using the disc? If so , then it could be the disc or the EBOOT! I had this problem with BO2 and I thought it was the EBOOT , but instead it was my disc , so I tried another disc and it worked without any problems! Maybe it'll work again if you try using another disc! Other than that I'm not sure what else to say , but it worked for me! Good luck!
