Is that the point where Tartarus knocks the Arbitor into the pit after recovering the Icon? If so, many people, including myself have had the same problem. To get past it, restart Halo, choose Campaign, and then click on Select Level instead of Resume. Select Gravemind, and it will continue on and you will continue to receive achievements. This only happened to me on Normal mode, worked fine on Hero mode.
