I bought the Escalation map pack for Black OPs, but it won't let me download it. I've tried the suggested actions but they haven't helped at all. There's nothing wrong with the internet connection and my PS3 gets on the internet without a problem, but error code 80710723 keeps popping up and the map pack will not download.
Any advice/help would be great!
The error code indicates a network connection time-out. That generally means that either some part of the network path between your ISP and the server, or the server itself, is very busy. Try downloading the map pack again later. The problem should get resolved by itself after a while.
