Can't enter dynasty mode and create player mode

Eversince i have installed NBA2007, i can't enter dynasty mode and create player mode. Whenever i try, nba2007.exe closes and exits. The rest area are all OK. Please, someone advice me what to do. Thanks.

Are any error message displayed when the game crashes? Also, what are your PC's specs?

i just figure it out lately. To enter dynasty mode, i should reset rosters first. If not reset, then enter dynasty, NBA.exe closes. Same thing in create player.

Does in dynasty mode, no overrated players are allowed? maybe that's the problem.

Anyway, here are my PC specs.

intel Pentium 4, 3Ghz cpu speed, 768mbRAM, 80Gb Hardisk capacity, 128mb video card.

The player ratings shouldn't matter, though if there's any problem with the roster files you were using (such as a corruption in one of the databases) you'll experiences crashes like that.
