I hadn't touched Halo 2 for a while but fancied getting round to completing the single player so started playing it again a week or so ago. It came up with an update which started downloading then when finished it went to restart but crashed. Ever since then when I go into Halo2 and go to Live it comes up saying I need to redownload an update as it is corrupted. There doesn't seem to be a way of doing this and I'd rather not risk losing any checkpoints as i'm right near the end.
Any ideas?
