finalize team list and do you have an even number of teams. I can't remember but I think there may be a "save changes" at the bottom. I know those are kind of simple-prob-already done but that's the only thing I can think of.
Completely botched our draft a week ago. No one could get in. Had to switch it to espn.com on the fly. Never again with yahoo for me after that. Hope it goes better for you!
