Please help me please, regards to loading roaster

Dear All, I have the PS3 2K10, I love it, first/only game in PS3.

I've download the Bulls 97 roaster, once I load the file, I can use this team in quick game.

But when I try to use this Bulls 97 team in "Season Mode", it does not work, it goes back to current Bulls roaster.

Can anyone teach me how to use Bulls 97 team in the season mode?

Thank you, I apprecaited.

If it is on the default bulls team then you have to load your roster before u start the season. There's also a chance that it was custom-made via Create team function of the game, and if that's the case u cant use it in season/association (I think)
