Ok, i updated my 360 with my friends cd of the new update (dec.) and updated it on my 360. After testing out my halo 2 and tom clancy games, it worked. Then I got my new HDTV 42 inch in my room, which has cable internet. So i plugged it and wanted to play some XBL. my PDZ works just fine, but when i pop in HALO 2 and Tom clancy games, it makes me update a xbox update, not 360 update. So, i was like "Ah, hell. Ill update" and so i did. Tom clancy games work, but HALO 2 doesnt. It let me download 1 map combo ( the 5 pack) , but when i try to download the rest, it wont let me. I reset and it still doenst work. I try the next day it for some reason, i tried it and it worked. Just when it got to around 89%, it crashes and says that i need to contact Mircosoft because the multiplayer map did not install properly. Wierd huh?
