game crashes after opening nba icon

my game crashes after i open the game, it will turn to black like it's loading then it will crash. pls help!

More info needed. Computer specs, patches installed and any modifications you've made yourself.

i installed some patches, but i deleted it, still doesn't work.
computer specs: Pentium 4 1.6Ghz,512mb Ram,GeForce FX5500256mb videocard.
and i deleted some unnecessary files that i've installed from sgsm, still no good.
HELP!

At this point I'd probably try a fresh installation, no patches, and see how that goes. If it's still not working we'll go from there.

PROBLEM SOLVED!
i reinstalled my nba then its now better than before.
tnx sir andrew!

No worries, glad to hear a fresh re-install worked out.
