Not able to load into online games

Whenever I try to load up clubs or a drop-in, or any other online game for that matter, it keeps kicking me out. I will load in, then it will show my favorite default team in the game instead of my clubs team and some other opponent, and then kick me out, saying "You lost your connection to your opponent." It is not my connection. It didn't even let me load into a practice match in clubs without doing the same thing. Please help.
