New Rookie Pack Compatible with Andrew's Releases?

I recently tried to download a few rookie packs and roster update to upgrade my rosters and now, my game crashes when I click "play game" in dynasty mode. Is there any way to fix this? I really want to play the updated rosters...but I don't know what releases are compatible with what?

Thanks,

Sounds like an issue with the roster itself, which would be something the person who created it needs to check out and fix as necessary.
