2kX Mod Tool not opening

[Guest]

I've recently gotten a new computer, so I was reinstalling all my modding stuff. For some reason, the NBA2kX Mod Tool is refusing to open after selecting the game version. I've tried reinstalling it a few times, and I have the latest version of Java. I'm running a fresh 64 bit Windows 7 install. Anyone have any ideas on what could be causing this and how I can fix it? It's run just fine on my other W7 machines. Thanks!
