This was a great post, understood all the instructions, but I'm having problems. I successfully transferred all the files, got the DLC and profile onto my xbox. I log in as my user name, then with a second controller log in as BlackOps Taco, then start black ops. It starts normally. I go to Zombies > Solo > and the maps arent there. Am I doing something wrong? I've done this multiple times now, following multiple peoples instructions, still no success.

Thanks really much for the link
