Question about updating roster

So i see people here upload a lot of roster updates and id like to know if theres any way i can use the updated rosters and continue playing my association that i have allrdy started? ..or do i need to start a new association every time i download one of these roster updates?

I'm not positive but I don't think updated rosters work with association mode. I updated rosters and it all stayed the same as when I started the season. Hopefully someone can come and clear this one up

crazy, You will have to start your association over to use your new rosters.

MrMakeEmAkRight, Updated rosters work in association mode. Did you make sure that they were loaded by the game before you started?
