I've noticed that there are a few other people who have made posts regarding this same issue.
My maps had been working fine until, I believe, Friday. Then I noticed the red message on the lower left side saying, "Playing with original maps only. Download all DLC content you are entitled to from the STORE in order to play on DLC maps."
I have paid for Premium Elite.
Any ideas on how I can fix this???
Solved! Go to solution
Have a look at this thread - http://community.eu.playstation.com/t5/Call-of-Dut
I realized I must have been missing something after talking to a friend and the thread you linked me to helped me find it by searching for "July Elite drops".
It's working like normal again now. ^_^
