The Good News: The New Map Pack 1 For Call of Duty World At War is available
The Bad News: I Payed For It, It Began Downloading, Then After 3 Mins, It Was Gone From My Acitve Downloads, No, It Had Not Finished Downloading as i Thought, Infact It Had Just Stopped, So I Went To My Memory To See If It Was There, It Was, But It Just Said Error, So I Went Back To The Marketplace To Try Again, Won't Let Me, Asks Me For Another 800MSP, WTF!!!!!!!

Xbox LIVE Billing issues

Currently, Xbox LIVE members may experience issues related to billing. That means difficulties with account recovery, account management, Marketplace functions and/or making purchases. Users who already have Microsoft Points in their account will be able to redeem them.  Until these issues are resolved, you will also be unable to sign in to Xbox.com, which includes posting in the forums and queuing up downloads on the Marketplace. All other areas of LIVE (matchmaking, friends lists, messaging etc.) are not affected.

The engineers are actively working to resolve the issues as quickly as possible. Keep an eye on the Xbox LIVE Status page in the support section of Xbox.com which will be updated when conditions change.

Thanks for your patience.

I better then not post my impressions of the map packs =p.

are these out on PSN?

On the COD WAW Forums some UK guys could download it.  But most part of Europe doesn't have it in the store.

so i should be able to get my MS points back?

It looks like Live Billing is a clusterfuck right now.
