I've got the same problem and I've checked all my rosters and turned injuries and suspensions off. Using datFly's most recent roster and I've spent the last couple weeks switching players around with current roster moves.
All the minor teams have at least 21 players, at least 10 fielders and 10 pitchers on all teams. I'm running WIn 7 but in XP compatibility so I get less crashes. But halfway into April of the first season when I have the Winston Salem Dash (playing with the White Sox rosters) against the Braves' single A team, it stays stuck and game crashes. I started a new season and simmed just through April but around the same time, 3rd week or so even using the standard schedule. I'm guessing I'm probably gonna have to reset the rosters and start over.
