@PrinceXXLI would really like if you made this roster for 2k12 and I think I know your issue. MLB 2k12 will only load if your computer is set to a date before MLB 2k13 came out. You can avert this by either changing your date back to 2011 in windows settings before launching, or what I do which is using a program called Beyondo. once the game gets into the main menu you can change your date back as it causes some programs to not work properly. Hope this helps!
