Halo Multiplayer Patch

[lordpython]

gee, I'm sorry, I didnt' know I had to add this part:

I AM PLAYING MY BACKUP OF HALO

I am on vacation and brought my backups incase I misplace my cd wallet

I have upgraded my Halo to version 1.04, but most of the servers I try to connect to in multiplayer say "Your CD Key is Invalid". Is there a patch out there that "upgrades" the CD Key?
