What worked for me, unfortunately you already tried. I had 10 roster files and for some reason, only 5 was showing up when I tried to start a ML. So after I replaced the 5th one, it finally showed up.

Another method that used to work for me would be to take the roster to Play Now, then quit the game after tipoff, but somebody said a couple posts ago, that the roster isn't playing nice with play now.
