Actually, are you okay? I don't see any 40 yrs old player in your transaction record.
By the way, you only play in the Div.5, those 30+ players you bought under $100K, its very useful at your stage, I don't know why you force them to retire.
You are not necessary to restart your game. Beside the top 3 seeds in your div. all other teams are robot, I don't see you have any money problem, you just keep read more and learn how to play BB is good enough.
