Could somebody please tell me how I can join a quickmatch game or optimatch game on xbox live for this game (ddr ultramix 4). I am doing what it says in the booklet but it still wont let me switch into one, all it lets me do is create my own game. So if anyone has any ideas or solutions I would love to hear them. Thanks.

There might not be anyone playing when your trying..... go to the developers website and see if there is a group that sets up times to play.
