REDitor II NBA 2K12 Association editing problem

[DonHarmider]

Hello.i am using REDitor with guru and MyFriend license.
I installed Albys RR3 and some dornas.Started association and am about 30 games in.
Now i tried to change player stats in the running Association,like ppg,rpg,apg,etc.
For example i open association file in REDitor ,go to player stats,try to find the according player i am searching.Then change for example fgs made and his total points to fit.When i load my association i can see the changes and even simulate a few games but when i siumalte a few weeks further or close to end of season or to end of season the game crashes all the time.I even managed one time to go to the palyoffs but after last game itr still crashes.I donkt know what i have to do or where my mistakes are.Do i have to change the team stats accordingly but how do i do it?Is it possible the career avarges of pervious years(example Durant ppg,apg,rebpg, change from last year somehow?)
I would be very thankful for any help

Thank you in advance
