I am having trouble with the game title: Call of Duty: Black Ops, Purchased on May 4th 2011.
I purchased the Escalation Map Pack using Microsoft Point's via my debit card.
The update left me unable to play:
2. Multiplayer (All of the maps, except firing range)
3. Zombies (Solo and Multiplayer)
The game is useless now, and I am demanding a refund for both the game and map-pack, or at least a fix to the problem.
