Bungie explains Halo 2 360 download issues
It seems that a few people are experiencing download issues regarding the new Halo 2 maps. Being the wonderful (and hauntingly beautiful) people that they are, Bungie has posted some handy instructions for downloading the maps problem free. The problems arise from 360 users that don't have a credit card associated with their account, which wasn't possible on the original Xbox. If you find yourself in this particular situation you must do the following (courtesy of Bungie.net):
1. In the Xbox Dashboard, select the profile that you want to modify, and then select Account Management.
2. Select Memberships.
3. Select the membership that you want to update.
4. Select Change Payment Options.
5. Select Add Credit Card.
6. Enter the credit card information for the card that you want to add. This can also be a debit or Visa (or similar) gift card, however, some restrictions may apply.
There is also an issue involving European users using PAL-60 TV standard. If you are using this standard and running your 360 over VGA, you will be unable to download the new maps. The solution is to hook up your 360 with a composite video cable to download the maps. Of course, you will need an ordinary television to do this.
Bungie has also listed the playlists that will feature the new maps. Expect the playlist update to arrive next week. In the meantime, the new maps will only be available for custom games. Hit the "read" link for the full story.
