Probably about every other day - I get this error after the score chart is shown at the end of the match, but before the lobby loads. When you press OK it goes to dashboard, and when I eject the game and put it back in it loads up just fine.
Anyone else experience this? Sign of RROD approaching? (Hope not, on third xbox now)
Contact Activision support. I just had a similar problem on the PS3.
I had to let her know what all numbers I had on some screen, then delete all BO2 files, eject the disc, shut off system and reset router... Then I had to turn the system back on and redownload the DLC map I had. Working now.
