I am having problems going online. I connect to xbox live and can play other games online like halo reach, but for some reason when I go to play COD Black Ops online it Won't go load after I hit xbox live. It doesn't load up the latest patch. I have an open NAT type, I'm hardlined, I cleared the system cache, and I even deleted the update to redownload it and still it doesn't help. I spent hours reseting my modem and router and sometimes it works. I don't know what else to do. Please someone help me.
