Is this a fictional or historical league? Did you alter your schedule in some way, and if so, exactly what did you do?
Just to make sure, is the Disable Playoffs option unchecked in the Options screen found under Game Setup->League Setup?
When you write that you simmed to the point when the playoffs were supposed to begin, do you mean that the regular season played out normally, or that there were no games played whatsoever during the regular season timeframe?
Have you tried simming out another year, just to see what happens? Does the Spring Training status ever disappear?
