Activision-Blizzard’s Call of Duty Modern Warfare 2 Stimulus Pack Doesn’t Work

Surprisingly, Activision-Blizzard (ATVI) is up today. Maybe all the older folks trading the stock have no idea that over the past couple hours one of the most viral stories on the web is that Call of Duty: Modern Warfare 2 just released a software “bonus pack” which apparently does not work on Microsoft’s (MSFT) Xbox.

If the fix isn’t out quickly, we’d be very concerned about how the stock could be affected in the short term.
