No, I'm not deleting my profile and starting over. All other games and their DLC work fine for me. Its the Higher Learning II DLC that doesn't unlock. Higher Learning I was working, not the second. And i have replayed them, multiple times and different modes. The H.L.II DLC owes me 5 different achievements. But, its all gravy now, guys. You got my money for the DLC and i got nothing back out of it. Already traded the game in for something else that works. So, no sweat guys. But i appreciate your attempts at suggesting things for me to try. Thanks.
