anytime i load up Chaos theory, and go to versus, it comes up with an error that states:
"there's a problem with the update of your game. pressing A will restart your xbox. the game will re-update at the next sign on."

it doesn't.
This is my all time favorite game, and im starting to miss being able to play it.
if anyone can help me, please PM me, or leave a message here.

I read a post where someone was having this problem and found that if they first logged out of their account, inserted the disc and let it update following the prompts that it updated.

Another one had you put in a different xbox title, get the update and then load SC.

Otherwise you may have to resort to deleting all of your SCCT game content and start from scratch.
