When you break a rule your permission to trade that particular account gets revoked. When you purchase a reset you are issued a new account. If you decide not to purchase a reset and wish to practice your trading some more before undertaking another assessment, so long as your data subscription is active you can trade on the market replay function in Trader Talent Pro  which always has the 5 days of rolling data available to practice on.
Depending on how you are managing your exchange data expiry you might also be able to trade on your original free trial account.
