dynasty salary problem

After updating all the rosters in nba live 07 to the current rosters from 2012 when I play dynasty mode many players start playing while still 15 etc and players are presumably on real life-like contracts. The problem is that after 2-3 seasons all teams have salary cap space -50 million or more, anyone knows how to fix it? or does it somehow go back to normal after a few years in e.g 2012(game )?

Try the Age Fix, which is included with the current roster. It will change the year of birth so that players are their correct ages, as of the 2012 season.
