Hei guys, I have a problem with cod mw3. I had 2 multiplayer  accounts, one for me and one for my brother. But suddenly, my nat type changed from strict to moderate. My brother couldn't go on his account, so we deleted my account. But now, when I make a new account, I can't go on it, and my brother still can't go on his one. My whole multiplayer part is down! What can I do??? My cod is for wii. Help me please.
