thanks....tried everything. Thought I would try to complete the spring training team roster and fielding that team, to see if would allow me to draft players to my new regular-season team. it didn't work from my computer, as it wouldn't let me draft players to my spring team, but i logged off there and logged in from my phone. that worked - i completed and fielded the spring team and now i can add draft players for my regular-season team as usual.
weird, but at least i was able to work around it. thanks, again.
