How many times have you tried it mabey it was one time. I would normally suggest restarting the level however a similar thing happened to me in WaW where I could not progress at breaking point I tried restarting but that did not work so I turned off the console and turned it back on it worked. If neither works I suggest looking at your disc possibly scrathed.
