NBA live 05 unlock 50000 dynasty points

I used this code and it worked. Only 1 problem - i want to do this again. When i type it in again, it says its already unlocked. Is there any Dbf editing or whatever so i can use this cheat code again.

I think you can use it only once per season..

yea only once, I dont know about once per season though, I havent gotten that far yet, i tried to put it in more than once and failed too

I think it's once a dynasty.

btw, does anyone know where the dbf for information about the dynasty points is stored?
