Can't join Suppression game mode in MAG?

I always play suppression on MAG but I tried to join the queue today and it says "The requested game could not be joined." I keep getting the same message every time i try to join. I've tried restarting the ps3, router, and game. I even tried it on my other character slot. Sometimes it'll join the queue for a second but then it'll give me the error message. Help?
