xbl wont update

ive got everything setup the way i want it finally, thanks to aid, now my problem is getting live to update. i put in flatout 2 and was able to connect to live with no problems, but when i tried to sign in with halo 2 it told me i needed to exit and update. it loaded ms dash and looked like it completed the update, but only to say Update failed: blah blah may have a dirty disk. how can i get this thing to update? perhaps i should mention that just pressing eject brings me to a blank black screen, not the ms dash board like i thought it would. thanks

 

disregard that, i figured it out
