Modern Warfare 2 - Stimulus Pack: Now Players are Hit With Billing Errors

So the Stimulus Pack for Modern Warfare 2 was released onto Xbox Live yesterday. Except, it was broken. That was because the DLC was launched before the necessary Title Update. Something that Microsoft's Xbox Live Operations team has called "a process failure on our part" on its blog.

"Once they had been released out of order, it wasn’t a simple thing for us to resolve," Microsoft team member '-e-' explains. "For a couple of hours the result was unpredictable but most people couldn’t get into a game through matchmaking. In technical terms, it was a big hairball that we had to unwind."

But the problems aren't over yet, as it was also confirmed that some players are experiencing issues with Xbox Live's billing system.

According to -e-, those who purchased pre-paid Microsoft Points cards for the Stimulus Pack are the worst off, with properly activated cards reporting back to the team as non-activated. "You haven’t done anything wrong, you won’t lose your money, and you don’t need to go back to the store – just hang in there and try again in a few hours," is the advice handed by the team.

Elsewhere in the Xbox Live billing world, -e- has revealed that there are also side-effects of the DLC's popularity that may result in redemption code errors on consoles and official websites.
