Custom team crash

I create two teams and I include everything - logos, scores, jerseys... in DBF, I enter all of the information needed to make a team. But when I play the two teams together, the game crashes without starting. What could've gone wrong?

EDIT: when I play an individual team with an already existing team (that was created in the original NBA Live 08), the game runs fine.

Either there are missing court files or perhaps the teams lack entries in location.dbf.
