Sorry, me again just realised your asking about madden 08, not fifa, fraid i can't help you there as i dont have the game, just ignore my last comment.

Tuh, yet another online problem, if afraid i don't know how to fix it but everyone seems to have similar problems, and lets face it fifa online could be so much better. What i have to do is keep trying over and over, leaving and starting.. eventually i get a game, usually when playing at home (host? maybe) anyway i hope you get sorted out. By the way please check out mu videos if you get chance,and rate and comment thanks.
