Modern Warfare 2 Stimulus Pack Is Live, But Broken [UPDATE 4]

Details are still sketchy, but we're getting a number of reports that the Call of Duty: Modern Warfare 2 map pack that hit this morning is not entirely working.

The Stimulus Pack delivered five new maps for the multiplayer portion of Activision's popular shooter for 1200 Microsoft Points. But readers are reporting a slew of problems with the pack that just went live this morning.

Issues reported include:

Multiplayer lobbies not working.
Images for maps not showing up.
No option to play private matches.

We've contacted Activision for comment and will update this story when we hear more.

Xbox 360's Larry Hryb says that Microsoft engineers are "already engaged and working on the MW2 Stimulus Pack Problem."

"The Stimulus Package needs a Title Update and it didn't go out properly. We're pushing it out now - it won't be long," he wrote on his Twitter feed about 7:30 a.m.

Update: The pack is now working.

Update 2: Now it appears that marchmaking isn't working on Xbox Live. Larry Hryb writes that the service is in a "bad state" right now and they're working quickly to resolve it.

Update 3: Microsoft's official support page is reporting that the map packs still aren't working and lists a slew of other things that Xbox Live users can't currently do:
Creating new Xbox LIVE accounts, managing those accounts, or recovering an account on a different console
Buying downloadable items from the Xbox 360 console, Xbox.com, or Games for Windows – LIVE
Paying for downloadable items with a credit card
Signing into Games for Windows – LIVE on a PC
Redeeming downloadable items with Microsoft Points, buying additional Microsoft Points, or viewing your points balance
Using prepaid cards or codes for downloadable items or Xbox LIVE subscriptions
Purchase transactions using the Games for Windows LIVE client.

Update 4: Modern Warfare 2 DLC is up and running. Live status is still suffering issues.
