Manually editing a tournament only updates the information in your database and the original files provided by your poker site are not changed at all by PokerTracker 4. If you've input a value such that this tournament in your database now exceeds your allowed stakes you will not see it in your reports anymore so if you want to fix that you are going to need to do this change outside of PokerTracker 4 using PGAdmin. If you've not used PGAdmin before you might want to
backup your poker data before making any changes there as making database changes outside of PokerTracker 4 isn't supported. Close PokerTracker 4 and then you can access PGAdmin by clicking your Windows Start button then typing:
pgadmin
and then clicking on it when it appears. Double click on 'PostgreSQL x.y' (where x.y is your PostgreSQL version) and if your prompted for a password the default is 'dbpass' (without the quotes). Next double click on 'Databases -> YOUR_DATABASE_NAME -> Schemas -> Public -> Tables'. Right-click on the 'tourney_summary' table, choose 'View Data -> View All Rows', find the relevant tournament, edit the value in the 'amt_buyin' column and save the change (File -> Save'). If you have trouble finding the tournament you can sort by the 'amt_buyin' column using 'Tools -> Sort/Filter'.
