Problem with Seattle All-time challenge moment in the Ruth program.

I go to load this moment so I can do it, and it says your opponent has an invalid roster. It will not let me do the moment. Any tips to fix this?

My problem the first time around with the M's was delivering a meatball of a pitch to the Bone. Second time around no issues.
