外网搜的,就是新的包和老的冲突了,删掉老的,只安装新的就可以了,试试吧。
Uninstall all the older multiplayer data packs, except the first multiplayer pack (6.0 GB). Also, delete the Warzone Data Pack 1 and Data Pack 2.
Now install the new multiplayer pack (22GB) and the new Spec Ops and Multiplayer combat pack.
This will allow you to access Multiplayer without any error.
